How to bypass the factory amp in a gmc yukon 2001 without a PAC device. what wires do i cut and splice in the factory harness to go directly to the aftermarket head unit?

Might be able to get an adaptor that plugs straight in painlessly.
Failing that it's the standard trace and identify method that eats time like crazy.

Hi Kacie.

Pretty much the only thing to do is remove the harness you spliced into the incorrect harness and use crimp connectors (the GOOD ones, not those cheap plastic blue ones) to match wire-for-wire and restore the original circuitry. THEN have at the correct harness and reinstall the stereo wiring. It's a PITA all right, but it really is the best way to fix your problem.

Sorry about the bad news...

The fuse is doing it's job. Saving the wiring harness from melting down into it's self and shorting out everthing next to it. No simple soultion. Some one need to get in there and find where the wire is shorted out. DON'T bypass or replace the fuse with some thing bigger. This will cause bigger problems & $$$$$$ down the road

I just built a factory amplifier/crossover bypass adapter for my 2002 Chevy Tahoe Z71 (non-Bose system) . This adapter will allow the full range of audio directly from your head unit to the door speakers. Without this adapter, the factory amplifier will cut out much of the bass / low frequency audio to the door speakers. This adapter will continue to provide an audio signal to the factory amplifier for the rear factory subwoofer and cargo area pillar speakers.


I have posted an article with complete set of step-by-step instructions and detailed photos of the build and installation process.

The article also includes direct links to the exact parts that I purchased on Amazon to build this bypass adapter.


This is what the end result looks like. It is a 100% non-destructive adapter than can be installed or removed from the Tahoe at any time. It just plugs in between the factory wiring harness and the factory amplifier.

Good Luck!

Sounds like a loose fuse, or bad ground in the wiring. Its pretty common that one fuse controls most of the internal electric components.

Depending on what radio you install you will need an installation kit so you can plug in your OEM wiring and not have to splice and decipher factory wiring. Check with Best Buy or Crutchfields' (online)

The stereo side of the wires should be labeled. Check out the12volt.com for a wiring schematic for the truck side. I advise against cutting and splicing wires for a stereo installation though. They make inexpensive harness adapters that will allow you to splice into the stereo harness without cutting into the factory wiring.

After time, the wires at the end of shifter break because they were cut short at factory and have little or no play. You will have to take column cover off where you can splice wire back together. It’s best to solder them together for best contact.

There is no remote wire on these newer trucks....03 and up....u have to buy the harness....although i didnt....i have an 03 gmc sierra and just pulled the schematic and matched the wires. And there is no programming to do on an aftermarket stereo.....I work for GMC and we cant program aftermarket stereos......if u buy the right harness ...and its over $100 then everything should work just fine.....and this does not disarm ur alarm system either....mine still works fine....hope this helps

You can not bypass you drls. I just put a hid kit in my 97 yukon. You have to buy a wireing harness that hooks into your harness currently on your truck. The only way to shut you dlrs off is you e brake
