Well I have been wanting a light bar on my truck for a while, decided to go with a Cree 180W spot / flood LED light bar from ebay, cost me a whopping $60 shipped. We will see how it holds up. if it doesnt hold up well then ill get a diff light. I will say though, for $60 it's pretty bright and cant wait to be able to use it on the trails to see how far it actually throws the light!

Thank you! I have kind of neglected it the past couple of years cause it was at my parents house. Now that I have her at my house I am going to start doing some TLC and I really would like to stick a cam in it in the near future, and heads too if I can swing it.

 

Do you have anything done to your 4th gen?

I bought it off of ebay, it is an epistar light bar, the leds are made by cree, allegedly. I was able to use the light bar tonight and it is pretty bright, I don't feel as if I am loosing too much, if any, light from it being behind the grille either.

 

here is a link to the one I have, but like I said, it is nothing special (i.e. rigid) but it is bright. only thing is to wait an see if it will hold up to the weather and not let moisture in.

What wiring harness did you use?

 

I did not use a pre-made wiring harness for a few different reasons. One is because they never give you enough wire. it's like they make the harness as if it's going on a honda civic or something. for instance my TRS HID kit I put on my truck I bought the wire harness from TRS thinking everything will fight nice and it saves me from having to cut / splice / worry about the relay and capacitor. well there are a few wires that are just a little too short, and it pisses me off. I could go in and cut and splice to make them longer but I did not.

 

This is how I wired all my stuff up and maybe this will help someone else who is looking for this information. it is really easy, just time consuming. Just take your time and double check all your work. I am just a backyard mechanic that works on cars every now and then. the whole install prob took me about 5 hours, but took my time, I was not in a rush to do anything. honestly the part that took me the longest was measuring; for my switch and the light bar placement.

 

here is a small write up on how I wired everything.

 

You will need some 14ga wire and you can use 16ga wire for you switch IF you are using a relay. butt splices, wire cutters, zip ties, and connectors to connect the wires to the relay and the "O" connectors for you grounds.

 

1. I ran a power wire from a fuse that has power whether the truck is on or off and it was on the drivers side of the dashboard (you have to pull that panel really freaking hard to get it off btw) to the power in terminal on the switch. I used 16ga wire for this as it has very little amps running through it.

 

2. then I grounded the switch since it has a small led light that turns on when my light bar is on. if your switch does not have a light then you do not need to ground it (I don't think). 16ga wire

 

3. then I ran the power out wire from the switch through my headliner, down the drivers side a-pillar, through the dash, and out of a grommet located on the floor in front of the drivers side seat. you have to pull the door jam trim off and pull the carpet back to see it. I wanted to go through the firewall with the rest of the wires from the inside of the truck but that was just too much of a PIA to do. this way is much easier and you cannot tell. once that wire is outside of the truck I ran mine down the frame rail up into the engine bay, down the drivers side front fender under the radiator support cover and to my relay (which is located there). I of course placed wire loom around the entire wire outside of the truck to keep it from being chaffed. 16ga and 14ga (only because I ran out of 16ga wire)

 

3. find a bolt to ground a wire to ground the relay. 14ga

 

4. run a wire to the + side of the battery and place an in-line fuse that is close to the batter, mine is about 6" - 12" away from the battery and then run that to where ever you place your relay. Also I used a 15 amp fuse for my light bar, follow the instructions on your light bar to figure out the fuse. but if yours does not have any like mine then just look up OHM's law. 14ga

 

5. place the + wire from the battery to pin 30. 14ga

 

6. place the power out wire from your switch to pin 85.

 

7. place the ground wire to pin 86. 14ga

 

8. place the + wire going to the light bar to pin 87. 14ga

 

9. If you are using a 5 pin relay like I did (it was laying around in my garage) then leave pin 87a empty, it does not get used.

 

10. I placed heat shrink over pin 87a and over all the other pins because my relay is just laying under the radiator cover and not bolted to anything and I did not want it to accident touch some metal and short it out. BUT it also helps weatherproof the relay.

Sadly after owning it for 15 years...I just sold it.

It had very few mods done to it - exhaust / suspension upgrades. Never did dig into the motor.

Sold it to local guy here in DFW that is part of the LS community. He is currently doing a few mods like intake /cam/ heads /etc.

Hello truck looks nice.. Do you have pics of how you mounted the light bar?? Any special brackets you used??

 

Thank you. I used a 3' x 6" piece of aluminum that I bought from Home Depot. I painted it black so you cant really see it, I then bolted the piece of aluminum to the radiator support bars. I then bolted the light bar to the piece of aluminum.

 

It was very easy to do, the hardest part was measuring, I measured and measured and then measured again just to be sure. I centered the light bar on the piece of aluminum before I mounted the aluminum. Then I centered the aluminum to the grille. I also used a level to make sure it was level.

 

To make sure the light bar is in the gap before I took the grille off I used a flat edge to mark the radiator support where the grille opening was. Once I had everything mounted up it was perfect. I did not have to make any adjustments and did not have to re-drill anything. again very easy but even more tedious.

When mounting there any issues with it being in the way of the rad? Also did you use the mounts that came with your bar?

No issues, just make sure if you mount to the radiator support that your drill bit is not long enough to puncture any of the radiator fins when you drill through the support. As far as airflow to the radiator i have not had any overheating issues and my fans do not appear to be coming on any higher or more frequent than before. however, i do not have any statistical data to back that statement up. i am sure it affects the airflow, but i dont think it affects it too much.

      Some Assembly is Required

      By Grumpy Bear · Posted

      www.enginelabs.com/news/what-i-learned-today-bearing-clearances-vs-oil-viscosities/     www.enginelabs.com/news/oil-viscosity-can-the-numbers-be-misleading/ The Big Lie… Coming full circle to the reason Lake discusses the Porsche engines in particular. Based on the 2000 samples in the SPEEDiagnostix database, increasing the oil viscosity in these engines, even those run on the track, showed no significant difference in results.   The smoking gun was in the oil chemistry. That is where the data shows higher instances of more wear. Molybdenum was the key; the higher the amount, the less the wear. Speed postulates that higher viscosity oils have more thickeners to artificially inflate their viscosity numbers. These thickeners lose viscosity under shear, and the result is that not all oils of the same viscosity have the same shear stability.   Having enough viscosity is the most important characteristic, but according to Speed, once that required viscosity level is reached, additive chemistry matters more than additional viscosity. Speed also states, oil pressure problems on the racetrack aren’t a viscosity problem; it’s an oiling system problem. Running a thicker oil is just a band-aid for an underlying oiling system problem.

      Can it still be Assembled II?   Viscosity on the decline by various means. Heat on the rise making that worse. Engine RPM in the tank. Smaller motors with more boost trying to emulate an electric motor. Full torque, zero rpm. Then we will triple the OCI. Argh.    But wait....there is more. LSPI has pushed a shift from Ca to Mg and as that cost more PLUS the run to lower sulfur compounds the TBN is moving in the wrong direction for the increased OCI's demanded.    That not being enough to placate a demand for a parameter they can't measure the other sulfur bearing compounds are also under attack. That would be zinc and phosphorus sulfonate compounds. To some degree those are being replaced with boron esters and others, i.e. titanium ect. All of which have shorter service lives. And there there is the "Secrete Sauce" marketing for AW adds that 'Can't be detected by UOA's" but trust me because I (the blenders) never ever lie.    Spoiler alert; ALL additives are sacrificial! Smaller amounts of the old blended with less robust versions of the new do not equal longer service lives. So what are the blenders recommending? Wait for it.......   MOVING THE GOAL POSTS! OMG      Let's declare the long standing TAN/TBN crossover irrelevant and tell people that soot is a great 'graphite' based lubricant which can aid tribo films. Wait, what? Let's declare that the standards used for oxidation and nitration were to conservative and can be expanded. Let's tell them that because GDI fuel dilution, although being a VISCOSITY KILLER and an acid generator is actually okay because we have better base oils that limit viscosity failure limits. (Said knowing this is measured in fractions of a centipoise and in bases not commonly used in shelf oils)   Lying from the heart is not just the new normal but we have a public, a very young public, that is so ignorant of the facts and so sure of their "RESEARCH" into AI driven models base in regurgitated  instead of scientific research based unvarnished, peer reviewed FACTS that the incoming guard is loosing their grip on reality and the OEM's are tickled pink while the blends bend the knee.    You have an ever limited set of tools to work with. And sooner or later those will be taken from you as the API and the EPA strangle the last remaining fluids from the system. What you have left is your wits. If you care to use them.    At some point in the very near future it will not longer be possible to do "What is best for the machine", and be replaced with "The best you have access too". You WILL be rewarded with half the life and twice the cost. That isn't that hard to predict.

      Software Update

      By Chuck FB · Posted

      I trust you saw the other comment where he knew what he was talking about !. Yes, these darned newer vehicles with all their so smart they are stupid technology, goes and drains the battery down. As you might see my other comment, I installed a Noco 5 battery tender under the hood and at this point still have the cord routed so I have to lift the hood and then plug it in but am typically parked in a garage or a shed so its not risking the engine hood in the wind. That way I am assured or hopefully so of not finding I have a battery drawn down and can't even start the truck and that also damages the battery to draw it down too far.

      I guess no surprise my guesses were wrong !, at least now I know if I ever happen to see it grayed out in my own truck as to what is going on.    I never happened to catch my truck with it grayed out, it seemed every time I would test to see if there was an update it never found anything and yet more than once I would check to see if there was an update and there was nothing, then a day later or even that same morning I would drive to town and after more than one engine shut down in town as I did my errands it would pop up that there is an update now ready to install and the only place I have a connection to the internet is at home by wifi so its not as if it grabbed the download while driving. I don't trust these new vehicles due to all the crap they can decide to do while sitting for some days not running and run the battery down so most of the time if I know the truck will sit for a few days I plug in the battery tender I have mounted under the hood and so the only time the truck must have downloaded software was when it was sitting in the garage where the signal is awful but I have that tender plugged in and somehow it managed to download it. I honestly detest all this crap, way to easy to leave a person stranded.    Since I don't trust any of it I don't do the install of the already downloaded software until I get home and sometimes have even sat in the truck to watch what its doing as its going through the process to its conclusion as its not like it is set up that it will tell you the next time you fire up the engine that the update that was initialed actually installed or installed properly. Yes I can go into the updates and see the list. After I go through the install where I feel its safe to do so in case it breaks down as a result, I will plug in the battery tender after the fact to recharge as I don't know how much power its taking just to do the install and that can take a while for it to install.

      Thanks for the reply. All settings were correct and the engine was off, as it was supposed to be. It turned out to be something simple. I took a drive for about an hour. I must have had a low battery without knowing it. The voltage gauge on the display looked ok. At the end of my drive, I shut off the engine and the update prompt came up and it updated normally. It’s ironic because one of the features of the update is a reduction of battery drain.
