Anyone have any issues with a power draw after the upfitter switch install?? My truck has had 2 completely drained batteries over the last 3 weeks, each time after a few days of not going anywhere. Fuses are placed to only allow power once ignition is on.

Hey all. Hoping someone who is more electrically savvy can give me some help. I recently installed the GM up fitter switches, followed the how-to I found on here and everything worked great, or so I thought. Recently my truck sat for a few days without starting and each time, the battery is completely drained (can’t even Auto Unlock doors. How do I start tracing down where the draw would be coming from? Does this mean I did something wrong or just have a bad connection somewhere? for what it’s worth, upfitter switches were configured to only have power when ignition is on, and were wired to a light bar in my front bumper. I also have factory headrest TVs that had to be spliced back into the new harness that came with the upfitter switches (screens were previously wired into that plug location). Any help is appreciated.

Following -- I just added 6112s on the highest setting and gained 1" up front. I realize its a bit outside the original intent of the thread, but this is a great starting point for looking at tire sizes that will fit.

6112s up front and 5160s in the rear! Controls body sway much better and gives the truck a more planted feel.

A few weeks ago I put on a Fab Fours Matrix bumper. Last night I finally got around to installing the GM upfitter switches and wired up the 30" led light bar.

Just did the complete install last night... to include completely removing the knee bolster. What a pain in the ***! This discussion was incredibly helpful as I have the center console and could not figure out how to get the lower trim off the radio area. Thanks to all who have contributed to the how-to!

I have a set of Husky liners that a purchased before realizing they wont fit the CarbonPro edition. If anyone is interested in purchasing, just message me.

2020 AT4 6.2 7700 miles. No window leak (fingers crossed) and no issues.

For what its worth, I ordered 6112s and 5160s from shockwarehouse.com yesterday. Both were in stock and shipped today... arrival is scheduled for Saturday.

2020 Sierra AT4 Carbon Pro. Cereamic tint all the way around, 5% visor on the front glass. stubby antenna, RXP twin can catch can, low profile UWS toolbox. Future -- FabFours Matrix bumper, level, new tires...

following for ideas. Good looking trucks yall!

Can anyone say if the 6112s are capable of handling the additional weight of a winch bumper? I have a Fab Fours Matrix bumper ordered and it weighs 150 lbs. Trying to avoid having additional squat up-front and increasing the already drastic rake. Truck is a 2020 Sierra 1500 AT4. Thanks.

Following -- I want to switch out the 6" oval steps that came on my 2020 AT4. The high clearance steps weren't available yet.

Following - I'll need the Aux switches once I get my FabFours bumper on for all the extras

I have a FabFours Matrix on order courtesy of the insurance company of the guy who hit me. Should be here and installed in 2-3 weeks. I'll post some pictures once its done. Not sure if its more bulky than you're looking for though.
