I hear ya, out of all the things that need logic and modules to control I don't think trailer lights should be one of them.
I've had a few deck owners too with light not working

Why did they have to add the active trailer bull chit lol

Just stupid

Same as this vip crap, had a 21 Tahoe all fawked up after a ebcm recall reprogram ffs, pulls my hair out lol

2.5 ya mean

It hauls more weight, and trucks come with the adapter to 2 inch at pdi time, so dealer is holding them or something

update, drinking whiskey is about the only progress i have made with this truck lol.

I've wired in a resistor, tried the curt adapter for LED lights, wired in 4 incandescent 2.5 inch marker lights in series with the other lights, wired in a 6 OHM resister lol.. I have check my amperage draw and have seen as much as 3 amps. From other responses on this forum, the truck needs to see 55ma draw. So in theory everything I've done should work but not the case.
If anyone has got a deck to light up on a 2020 chev or GM, please chime in.

My last resort is to into splice into my taillights to take power but I'm worried that may cause the body control module to act up..

Whiskey is a good start. Are you wiring in the resistor/bubs into the brake/turn lamp? or park?

I believe others have wired into the taillight harness without issue but don't quote me on that

Anyone notice their lights on their deck flickering when the truck is off? I have a 2019 GMC 1500 (don't call the half-ton-sled-deck-police on me I only use it to haul one sled). I have a Marlon that has a 4-pin plug and plugged into a converter to 7 pin to keep the truck from thinking the tail lights are burnt out so I don't get any codes anymore except it does turn off all my back up alarms because it thinks there's a trailer back there but I do notice the lights flicker randomly when it's parked in the driveway.

It's part of the anti-theft system. It sends power through the trailer lighting circuit to make sure the trailer is still there and LED lights take so little amperage to run that they'll flash when it does. Incandescent bulbs won't.

Its 2020, you would think a manufacturer would of figured this out already, I dont think it would matter if it was a sled deck or a trailer, thats a 2005 problem.
