Reverse, Cargo and Mirror Lights All On

[aleeuw]

Hi All,

 

Just picked up a new 2022 GMC HD and the first thing I noticed I am missing from my 2018 Silverado was the jumper in the BCM for cargo and mirror lights on in reverse. I searched in here but couldn't find anything. Does anyone know what wires to jump to make this happen like the K2 versions?

 

Thanks!

Not sure about your bed cargo light.

Looking at the kit, im wondering is the diode needed? Im thinking just run a jumper from reverse to cargo  Lights, what could go wrong?

Put the truck in reverse and the cargo lights come on with no way to turn them off - might cause a glare.

I did this with my 2019 HD and had no problem worked great for 3 years. I'm going to do it to my 2022 very soon.
