RED WOLF Stereo Wiring Harness Fit for 2002-2008 GMC Envoy Sierra Chevy Silverado Impala Aftermarket Stereo Radio Wire Cable Connector Adapter

Great plug fitting, good color coded wires

De buena calidad

Low cost and delivered quickly. The product functioned as described.

Didn’t work for 2004 Pontiac Montana due to certain wires not being lined up with adapter may work for other models though.

Nice looking product but did not fit the application on my truck. Wound up having to find an oem wiring diagram and change all the pins around to make it work.

Just what I need to hook my new stereo up in my van

So, for all intensive purposes, it works. Harness connector fits the factory plug, speakers are correct, power is correct, but the factory wiring does not have a 12v acc wire present, and you gotta have that for the unit to power up. This won't be an easy job for a beginner, and it was a bit of a pain for me, and I'd consider myself intermediate. The broken English in the instructions doesn't help...at all. A little research, and I found what I needed...which required a trip to the big box home improvement store. It started feeling like a "free" puppy $50 later.You're going to need a voltmeter, something to jump off of your fuse box (make sure you don't jump off of anything necessary for vehicle operation, and don't jump off of something that is continuously powered,) a little ingenuity, YouTube, anger management courses, NyQuil (so you can sleep at night and not think about why your radio isn't working,) lots of beer, and a strong vocabulary of curse words.Once you've ran that wire, it will attach to the red acc 12v wire from your new unit's harness. If you wired everything properly, you will have a working unit.You can search YouTube for "acc wire from fuse panel," and you should find what you need for that.I also ended up using a previously installed XM radio acc wire because the one supplied was too short. That's also why you'll need anger management courses.Keep in mind, no matter what harness you buy, you'll have this problem. This isn't an error on Red Wolf's part. But their instructions were garbage, and helped zero.Hope this helps, and be sure to just go ahead and get about 20-25 ft of similar gauge wire for your acc from the fuse panel. It's cheap, and it's better to have too much than not enough.
