RED WOLF Car Aftermarket Radio Stereo Wiring Harness Adapter Connector Compatible with 2006-2013 Chevy GMC Express Savana Buick

The instructions that come with this are very vague they say to please correct the pins, if they do not match up, but it does not show how to switch the pin over to a different spot. A few of my pins on my 2007 Silverado did not line up with the factory harness and the red wire for the switched power was not even close to being long enough to run to the fuse box. I’m guessing since they added the red cable for the switch 12 V power they are aware that the harness for the radio does not come with one and needs to be fused tapped. After doing some research after 2006 Silverado‘s do not have fuses that are switch powered all fuses are constant or only work when the button is being pressed. It took me looking in various forums to find out why my radio was not turning on, which is because, the factory radios turn on due to signals being sent through the harness and not direct 12 V switched power. This information would’ve been very helpful and saved me a lot of time maybe even would’ve thought twice about buying an adapter harness and instead buying an interface, which would’ve eliminated this whole problem. After all the slight modifications, the harness ended up fulfilling its purpose (ONLY, because I made it work, I do thank amazons annoyingly long return/refund process as motivation to not give up trying) but I feel it’s some thing the seller should mention when showing the compatibility for vehicles. Unless I’m the only person that ran into this problem while having a 1 in a million kinda truck ***Edited*** So after months of frequently replacing LED and HID bulbs for my headlights since the daytime, running light fuse was the closest thing to a switch powered fuse, and not a constant I actually found a hidden spot that is switch powered for the 07-13 model Silverado's, behind the hood latch near the brake pedal there’s a small box with a cover on it that has a picture of a battery on it So I have to take back what I said since the red 12V switch cable does reach the spot I found that works best now. I believe it’s the second row from the bottom up and the second spot from left to right I’ll try to remember to take a picture when there’s some day light

However it does not for fit 2011 gmc terrain.

Worked perfectly in my 2012 Impala without swapping pins or anything. Had to plug the switched power into the window relay though. Car issue not the harness.

Perfect fit easy to install would recommend this radio harness

For a 2012 Chevy Tahoe this harness does work however if you are using an additional steering wheel control then you will need to make a change. On the PAC you need to have a wire in Pin 13 ( green wire on vehicle) but this harness has nothing in Pin 13 and Red Wolf placed a pin wire (pink) in Pin 14. On the Tahoe you do not need a wire in pin 14. You will need to move the pink wire in this harness from Pin 14 (which is not used on a 2012 Tahoe) and put it in Pin 13. Once you do that wire up per instructions and you will have working steering wheel controls too. For reference, you will need an ignition power wire run outside of the harness. Red Wolf does not provide a long enough wire so you will need to tap into fuse box under the hood and run power from a 15 amp switched fuse (using a fuse tap) all the way to the radio.
