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!

Hi, my research indicates you can install a single din aftermarket head unit in the 2001 Yukon.
A couple of good websites to use are crutchfield and modifiedlife.
Crutchfields will identify exactly what adapters are needed, and modified life has the factory wire colors.
You will need an adapter to fill the space between the aftermarket stereo and the hole left by removing the factory head unit.
You will also need an antenna plug adapter.
I recommend you buy the wire harness pigtail to simplify the installation--this may or may not include the antenna plug adapter.
If you have onstar, you will need an additional adapter.
If you have steering wheel controls, you will need another adapter to keep those.
Keep the above things in mind when selecting a new aftermarket stereo, as you will need one that is compatible with steering wheel controls and onstar, if you have either of those and want them to continue to work with the new stereo.
Crutchfield has an link called "outfit my car" that takes you through a "Turbo tax" style questionaire and tells you what will work and what you will need. here is the link: http://www.crutchfield.com/App/Car/outfitmycar/MyCar.aspx

Assuming you have a base Yukon, here are your factory wire colors from modifiedlife.com:

Please let me know if you have questions, and thanks for using FixYa.

Hi, pull the trim plate off the dash around the radio. The trim may go all around the instrument panel. With the trim plate off, you can see the factory radio screws. Take the screws out, pull the radio out and remove the connectors, including the antenna wire.
You will need an adapter to fit the aftermarket radio snugly into the dash. They sell these wherever they sell aftermarket radios. I recommend you also buy the cable adapter. If you don't, at least buy the antenna adapter of you will no be able to plug your antenna into the new CD player.
Follow the instructions on putting the adapter together--it's made for a lot of different cars. You need it to screw into your dash where the screws came out.
If you buy the wire adapter, follow the directions that come with it. I recommend you solder the wires, but you can use those crimp connectors if you don't have soldering equipment.
If you don't buy the adapter cable, use the factory wire colors below to match up the aftermarket wires to your factory wires. Wrap any solder connections with electrical tape and carefully plug everything back in, including the antenna adapter and antenna cable. With the adapter plate attached to the new player, carefully push the wiring aside to get the player into the slot and then screw it in. check the system for proper operation and then replace the trim panel.
Enjoy your CDs, and let me know if you have any questions.

following is the procedure. u can also check ehow for more details.

Twist the negative cable off the terminal on the vehicle battery, using an adjustable wrench.

Remove the factory issue stereo. Pry off the radio trim bezel with a flat head screwdriver. Remove the four bolts on each corner of the radio. Pull the radio out the dashboard. Unplug the thick black radio antenna cable. Disconnect the wire harnesses from the rear of the stereo. Place the old stereo to one side.

Prepare the dashboard for the new stereo. Fit the radio installation sleeve provided with the aftermarket stereo to the radio installation kit. Feed the sleeve through the portal of the radio installation kit and bend the tabs on the sides of the sleeve to secure it in place. Feed the audio wiring of the Jeep and the radio antenna cable through the portal of the assembly and slide the assembly into the dashboard. Secure it in place with the bolts removed earlier.

Wire the new stereo. Connect the wiring of the stereo to the audio wiring of the Patriot, using a custom wire harness adapter. Push the connections together until they snap into place and test the connection by tugging gently on either end.

Plug the radio antenna cable into the alloted port on the rear of the aftermarket head unit.

Slide the connected aftermarket stereo into the prepared housing in the Patriot's dashboard. Click it into place in the radio installation sleeve, taking care not to trap any wiring.

cannot find 97 but found 98. Do these match?

Check the right wiring diagram for all speakers...



Hope this help; TY for using Fixya (remember cmment and rated this).

You need to attach the blue wire on the stereo harness to the blue and white wire on the car adapter harness. they installed a small amplifier to power the rear door speakers and unless you connect those two wires then the speakers will not work.

The factory wiring connector hook-up for the Mustang is:

Radio / Power Connector:

Light Green / Yellow - Hot at all times (Fuse 8)
Yellow / Black - Hot in ACC or Run (Fuse 11)
Light Brown / Red - Goes to instrument panel dimming rheostat (Fuse 4)
Red - Ground
White / Purple - Hot in ACC or Run (Fuse 11)

Speaker Connector:

White / Light Green - (+) Right Instrument Panel & Door Speaker
Dark Green / Orange - (-) Right Instrument Panel & Door Speaker
Brown / Pink - (+) Right Rear Speaker
Pink / Light Brown - (-) Right Rear Speaker
Pink / Light Green - (+) Left Rear Speaker
Tan / Yellow - (-) Left Rear Speaker
Light Brown / White - (+) Left Instrument Panel & Door Speaker
Orange / Light Green - (-) Left Instrument Panel & Door Speaker

Your best bet is to buy a radio install kit and adapt it to the Mustang connector. Hope this information helps.
