Yeah. I've read through them. Ordered one. Does yours light the dash or the swich?

When you do the latching relay, it will only light the switch. I wish it did light the dash, but as brights as the lights are, I definately know they are on.

Have you seen the Michael J Fox Edition Sierra/Silverado rolling down the road? Looks like the Toyota from Back to the Future. Anyway there is a really cool headlight switch with the option for Off-Ro

For you guys with 2014/2015 or anyone else that this doesn’t work for (due to BCMs not being programmed to output these triggers), please be patient with us. We have an alternate method that allows

Ok folks, for anyone wanting this headlight switch harness, I have them ready made, and ready to ship.   $35 shipped anywhere in the US.   They are built with the same specs as shown in the vide

Thanks.  I was hoping someone had figured out how to make it light the dash icon.

My hat is off to Tinkering Fox and Phil Gamboa. The video is fantastic.  I have a 2018 Sierra SLT and ordered the switch and made the harness (sorry Phil).  At first it didn't work, nothing coming out of the X5:5 BCM connector and no indicator light on the instrument panel.  After checking continuity I found that I had to reorient my new X1:12 connector.  I had to turn it 180 degrees in the X1 (white) plug.  Evidently it wasn't making good contact with the BCM pin.  Once I did this, everything works like it should.  If you have issues, check for continuity at each connector.  You can check continuity on the ground (-) signals with you multimeter.  The yellow wire in Tinkering Fox's drawing X5:5 is a +12v signal.  Keep in mind that the BCM triggers (turns on) with a ground, not a positive voltage. I also installed an interposing momentary relay for the high beams to interupt the power to the off road light, so there is no delay in killing my lightbar when meeting oncoming traffic.  I would still like to know how Tinkering Fox knows what functions are in the factory BCM programming and the pin placements.  I can't find any of this information in the Upfitters guides.  Great job guys!

Finally got around to contacting Tasca. Switch has shipped. Looks like I'll have a spare blue one for sale, when it gets here. I'm going to recheck my terminals thanks Phlash.

 

Guess what. My gray wire wasn't in correctly.

Now. Waiting to try again to install the light bar, when I get the bracket kit from Rough Country.  Tried on Sunday. Just didn't have what I needed to make it work.

Oh man, that's not bad at all.  I'm going to call them up to order one.  Thanks for the info.   

 

Shoot me a PM with how much you are looking to get for your extra switch.  I might be interested in it.

      New to Me 2010 SLE (Quirks, Issues)

      By fm2176 · Posted

      Thanks to the convenience of Amazon, I was able to get a few things done to the truck today.  I installed Carquest Premium oil and air filters with five quarts of Mobil1 High Mileage 10-30 along with a quart of Pennzoil Platinum 5w-30 I already had.  The latch for the flip up center console lid was broken so I replaced it along with the power mirror switch.  I found my push retainer assortment this morning and reattached the plastic under the bumper and it was only held on with a few screws and retainers.  Then I programmed a new remote keyless entry fob so I can lock my dog in the truck when I take her out with me (I've got to keep the air going for her since it's been in the 100s).  Finally, I ordered some LED interior bulbs and replaced the reading lamps.  The front lights are working fine while one of the back lights only works intermittently and the other not at all.   While under the truck, I found the source of at least one of the noises: the sway bar links need replacing.  I ordered a set of Suspension Dudes links with Code Red bushings.  Never heard of them, but they're made in the USA and have decent reviews.  While making yet another Amazon order, I went ahead and added a set of front tow hooks.  I went with red, since that's the color of the sway bar link and bushings and it should look decent enough on a black and chrome truck.  Speaking of which, it doesn't bug me much, but the passenger side mirror has a chrome cap while the driver side doesn't, so eventually I'll make them match one way or another.  Oh, and I ordered a $20 TPMS reset tool.  No idea if it will do anything for my sensors but it was cheap and will work for the Ford Transit Connect as well.     For tradition's sake, I ordered a new oil change wrench.  I kept the Snap-On 9/16"x15mm GM wrench I bought when I was 18 in the 2006 GMC from the time I bought that truck until the truck was lost.  While I was tempted, there's no need to spend $80 for a new SO wrench, or even $50 with shipping for a used one on Ebay.  I just bought a Duratech 15mm extra-long ratcheting wrench to do the job as needed.  It works, and if I like that wrench enough, I'll buy the set.

      Multigate electrical problem

      By Another JR · Posted

      The recall is for exactly this issue - those drain holes combined with the limited environmental capability of the tailgate electronics card inside the tailgate were a problem. The “safety issue” was the potential for the tailgate to spontaneously open, but all kinds of tailgate misbehavior can occur from water contamination of that control card.    There is no real fix yet. The initial recall just disabled the tailgate. Later, when parts became available, they would replace bad parts with new parts of the same bad design. My dealer is going nuts because the few times I let them get their hands on my truck, my tailgate is off due to a slide-in camper installation. They really want to cut my tailgate wires, but I won’t give them the chance. I will let them get their dirty hands on it when a real fix (redesign) is available.  My tailgate, which works just fine with sealant plugging the drain holes, will remain safe in a dry storage crate until then.

      Yes your absolutely right, I been looking at the 4 inch BDS one and it acutely states you can use the stock 20’s just not the 17’s or 18’s, I also didn’t realize that with my 275/60r20 stock wheels I’m already running 33 inch diameter wheel setup lol so I can just run my stock wheels and tires atleast to start.

      I would expect that to be lift-kit dependent.  If the kit has interference issues w stock wheels, then the kit/manufacturer should indicate that somewhere.

      That’s what I’m wondering is if the stock backspacing of the factory wheels will clear new upper control arms and such
