IOB radio wiring diagram?

[firedab]

I have searched and searched and cannot find the wiring diagram for this new radio! I'm trying to add a small sub to my daughters truck and want to tap into the wires behind the radio. Anyone know where I can find this info?

Thanks!

Dealer service or parts dept. I would tread carefully with these newer radios. Guy on one of the Camaro forums had a shop install some audio stuff and ran into poor sound and problems with the factory radio/hmi hardware.

 

GM does sell a very nice Kicker supplied sub/amp combo with instructions 19355508 for the IOB radio. IMO, that's the only way I'd go as its engineered to work no issues.

Left front...Blue +. Brown/blue -

Right front...Yellow. Yellow/black

Left rear...Green. Green/black

Right rear...white. Blue/black.

 

This is for a crew cab. I assume the double cab is the same. If your just doing a sub I would tap into the rear at the "B" pillar. Its pretty easy to get to.

If you're going behind the radio these wires are in the green plug on the far left.

i own a 2018 gmc and the right rear looks to be white and purple with black stripe
