NOTE: NOT COMPATIBLE WITH AMP SYSTEMS LIKE BOSE, INFINITY, etc.; Red wiring is not for all models, but if the OEM radio harness of your vehicle does not have an ignition wire, the aftermarket stereo cannot be turned off and on through the OEM radio harness. To solve this problem, you need to get a 12v power supply from the ignition by running the red cable separately from the factory radio harness

Works for 03 avalance
What to know is that the factory harness in the truck has not accessory power wire so the jumper that comes with this harness is very I’mportant tie all wires in to new harness besides the red wire on new harness you will jump this wire from an accessory wire coming from your ac control panel. You will need a volt meter to find the wire you need start by checking with switch off for a constant which will have 12v with switch off than turn switch on and hunt for another wire that reads around 12v this will be your jumper wire. Hope this helps.

04 Silverado…ehhh…it can work.
So, for all intents and 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.

The way to go when replacing a stereo. No cutting of the stock harness. Wire colours all lined up with my aftermarket Kkmoon deck.

Didn’t fit my truck like it said it would! Very annoyed. There was no point in returning and getting it changed as it would just take more time and money. Should just be taken down as it doesn’t fit the stuff it says it does!

Used this to install a pioneer stereo into my 2005 sierra 2500HD w/ boseIt worked – but one of the wires (12v switched) was incorrect and comes from a second harness, which this didn’t include. A wiring diagram would’ve been helpful, which is not included with the product.Everything else worked and was right, and the second harness only has 3 wires so it was easy to locate the one with switched power.

This wiring harness clips in perfect in my 2005 Pontiac Sunfire and the wires were pre stripped, can’t wait to get my deck in!
