For those of you that used a wire for this mod - what gauge solid wire did you use?

 

I'm assuming you used solid wire to be able to push it in?

 

Or did you just solder tin up some stranded wire?

I used 2 strands of solid cat5 wire twisted

Okay so I was inspired by 2 threads here, one being the fog lights on with high beams, which I did and love. The other is a thread about putting a switch in the bed by the tailgate to turn on the car

Hello,   Good idea, but I took your step little different. I have the puddle light and I tapped into that.     This way, when vehicle is in "run" position, puddle lights and the cargo lights w

only way will be to use an aftermarket switch. Buddy of mine, whom is also a member on the forum, did it on his 1500.

 

you'll need to use a momentary (or latching switch, whichever you prefer) and attach it to a power feed, use a diode to prevent back-feeding from the switch to power, then run the switch and again, diode to the cargo light circuit at the BCM, preventing any back-feeding from the BCM to switch. This should ensure that nothing can be back-fed and fried.

Mike 1220, do you think this technic would work on cargo lights as well?

yep, it will. I haven't tried it myself but see now reason why it wouldn't work. My buddy ultimately attached his to the reverse lights not the cargos, but the same principle should apply. For cargos just wire it the way I described earlier and it should work as you want.

Quick Question, needing to do this mod and I'm thinking of just using a wire to have them go on in reverse and when i hit cargo lights.

 

The thing is i have factory installed Max Trailer mirrors with the LED lights. will these go on in reverse and when i hit my unlock button?

If you use a wire, yes they will turn on at night when you click the unlock button. I wouldn't do it with a wire tho, because when you are parked and you click the cargo light button, the rest will power on because in a wire current can flow both ways. That's why everyone is using diodes, power only flows one way.

I figured that would be the case, was hoping they were on a different pin in the harness. I'm not trying to illuminate the entire parking lot overtime i unlock the truck with those things.

 

i just ordered the diodes off eBay. hopefully will have them by the weekend

I really hate to ask this but is there anyway you could sketch this setup down so it can be understood a little better. My electronics class in college was 30 some years ago and it's all just a little fuzzy to me if you know what I mean.

Kinda of not sure of how to wire the switch.

Sure can. Send me a PM if you don't mind so I can remember to do it later after my test today

I may have missed it but did anyone figure out how to get the cargo light to come on in drive and reverse on the early 2015s when you push the button. I saw that you can get them to come on with the reverse lights and that seems easy enough but i don't want that much light every time I back up.

I'm with Derbaby, someone help us figure out how to get the towing mirror lights and the cargo lights to come on while in Drive without shifting to Neutral.

 

Thank you again to those who've figured out how to get the fog lights to stay on with high beams and the cargo lights with reverse lights, now, just this last missing piece of the puzzle.

So on a 15, can I do this mod and the reverse lights come on with the cargo light button? My truck will already let me use the cargo lights while in reverse but It would be nice to have the reverse lights come on when parked and loading up the back of the truck.

 

Also, do you guys know if I can change the cargo lights over to led? I changed the reverse lighting to led and like the color and brightness a lot better.

Yes, RhinoGuy. I that's what the 11 pages of conversation were about.

 

And yes, again, the same bulbs for the reverse lights are in the cargo lights, so change away, as I've done with both.

If you were to put another diode in the opposite direction, then would it allow the reverse light to come on with the cargo lamps when you turn it on via the cab switch since the 2nd resistor would allow the electricity to flow the opposite way of the original?

 

I am curious becuase I am getting ready to add a VLEDs license plate frame light to add 3500 lumens when in reverse

 

If the second diode idea works, then I can hook up the light to either the cargo or the reverse, if it wouldn't work, then I would rather hook the light to the cargo lamps so I can use the light at night when I use the cargo lamps.

Mike 1220 I was interested to know if running a second diode the other way worked for turning the reverse lamps on via the cargo lamp switch inside the cab. I currently have the diode running the way El Conquistador showed above. This worked for having the cargo lamps activate when the truck was put into reverse. I have LED pods under the back bumper and wanted to be able to turn them on with the switch inside the cab, not just by putting the truck into reverse.

 

Thanks in advance

      OCI, not when but why?

      By PunchT37 · Posted

      My brother has a 2007 Avalanche with afm 5.3. It`s got 176,000 miles. Runs like a clock. Never been apart. Co worker has a 2010 Tahoe with afm 5.3. 230,000 miles. Never been apart. Runs like a clock. So, even though cyl deac is a weak spot, they can go the distance.   BUT, these engines had the oil changed regularly, AND had 5w30 as spec. I wonder if they would have lasted this far on 0w20? I`ll bet not.

      OCI, not when but why?

      By Chuck FB · Posted

      I certainly could be wrong but I hear of pickups far newer than that 2007 cutoff which may not be going to the wrecker but are having engine work done and be that a reman engine or new engine or trying to repair the existing engine. Some of it would be design issues as per the cylinder deactivation system that GM has and one of those lifters wiping out the cam and the question of oil changes moving the needle or not on that whole mess, or in the case of Ford pickup engines that have the long timing chains and wearing them out and the roller followers and phasers and some of that certainly goes back to oil change intervals. But in those various cases the truck has all sorts of life left in it and so the unfortunate owner and may be original owner or used market owner that is pouring money into repairs so the truck is not seeing the salvage yard yet but damage is happening by infrequent oil changes. A friends son had bought a 2018 I think it is half ton GM and it had some sort of extended or used dealer warranty on it and of course the lifter issue bites and its rattling and so the dealer had to swallow the bill and was at least 7000.00 and I think they only replaced what they felt they had to replace so yeah, I can see that being a ticking time bomb in the not too distant future. Would frequent oil changes cure all these engineering "marvels", probably not but some engine designs have shown that they do much better if the oil is changed a lot more often then if the manufacturer service claims are followed. New trucks cost so much that there is an incentive to keep the existing truck on the road by repairing.

      Tranmission stays in Low

      get a good code reader, and find out what problems the truck has noticed by reading codes. cheap ones can only get basic engine codes, you may want to get one that can get codes from all the computers in your truck.

      This is sort of my point, salvage yards aren't overflowing with all these 'poorly' maintained trucks - excellent/good/servicable condition otherwise, salvaged only as a result of a bad engine from poor oil change regiment.    In my area, there are no 2007 to newer gm trucks/suvs in any salvage yards. A few are in the 'recyclers' with very obvious reasons for being there - wrecked.

      Stabilitrak conversion to Z71

      By asilverblazer · Posted

      Stabilitrack was a stability control, traction control system, that functioned independently from the transfer case.   Z-71 has nothing to do with the transfer case or differential.   If it does have an AWD system, my memory recalls this being specific to the Denali trim, converting won't be as simple as swapping out mechanical parts like differentials and transfer cases. It will require reprogramming at a minimum. Long story short, not likely worth it.   Pulling a fuse, may disable the AWD system, it might also prevent any other transfer case functions.   However, the AWD case was generally based on the same transfer case you refer to in the 2006 Suburban. If it still has a 4-High and 4-Low where the transfer case locks and splits power 50-50 front to rear, what are you gaining by changing anything? A true-rear wheel drive only, what good will that serve? Not enough to go through the trouble of changing out all the parts.    Generally, all the factory systems will handle a 33" tire and re-gearing. Probably a 35" tire too, if you aren't driving like a caveman. If 35" tires are in the plan...   If you do plan on driving like a caveman or are fully committed to 35" tires, an entire re-think of the build is probably in order. Starting with square one, an IFS front end isn't going to be the best starting point for 35's and caveman driving.
