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.

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

Perhaps@GTPprix knows something about this on the cluster

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.

How much was the Rough Country bracket kit?

$38.26, shipped, I believe. It is not on the website to order. You have to call them. Part #70620

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. 

[Lnafree]

Yep. No problem
