You will need to purchase a separate module that will allow the factory options that originally are routed through the radio to still work. Believe it or not, many GM vehicles will not start with the factory radio removed unless the separate emulator installed.

Dave,

You will need to go buy a wiring harness adapter from your local Walmart (usually cheapest there) or Local Electronics place (ie Best Buy). The wire harness that goes out from the radio goes into the Adapter and the adapter plugs into the car harnesses. Also these Adapters come with the wiring diagrams for your vehicle. They typically run 10 - 15 bucks depending on where you get them. Thanks for using FixYa!

Sincerely,

JC

SOURCE: trying to figure out if

yes, the special harness is to convert the connection from your truck to fit the connection on the radio. the other option is to cut the harness off the truck a manualy connect all the wires. but trust me from experance. its worth the 20-25 dollars for the harness to save about an hour on the time to install it plus the hassle. not to mention is more of a profesinoal job and alot easier. you can get this part at any circuit city or best buy in the radio installation dept.

Go to this site...very helpful. You have to run your own power wire to power the aftermarket radio. I just finished an install 20 minutes ago.

I have a 2003 chevy silverado 1500, im trying to install an aftermarket radio. the problem im haveing is the factory wireing harness only has 11 colored wires. and no description. im how can i tell what...


DONT CUT ANY. Get an adapter from car toys or amazon etc. IF you do cut it, make sure you leave room to put it back on. The Chevrolet uses the radio for onstar and body information and you are in trouble if you make a mistake

Silverado radio wiring


Some trucks and gm cars have two kinds of systems one without a amp,and one without so judging by what you're saying you probably have one with a amp so yes you can but it is complicated and you would need to bypass amp so just get the kit that's required for your vehicle.

Can you put a newer radio in a 2001 yukon


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:
2001 GMC Yukon Car Radio Wiring Schematic
Car Radio Battery Constant 12v+ Wire: Orange
Car Radio Accessory Switched 12v+ Wire: Yellow
Car Radio Ground Wire: Black

Car Stereo Antenna Trigger Wire: N/A
Car Stereo Amp Trigger Wire: N/A
Car Stereo Amplifier Location: N/A
Car Audio Front Speakers Size: N/A

Left Front Speaker Positive Wire (+): Tan
Left Front Speaker Negative Wire (-): Gray
Right Front Speaker Positive Wire (+): Light Green

2005 town and country factory stereo removal


It's actually not too hard when you figure everything out. I just installed an aftermarket stereo and couldn't get any sound until I stumbled across a solution on this site. First you need to get the correct wire harness which I bought on ebay for $1.99. Then you need to get the install kit. I got mine at Radio Shack for $10.00 cause they're going out of business. You can get it at Best Buy too or any other car stereo place. To get the old stereo out. Take out the cup holder. There is a button on the top rear of it that releases it. Then remove the 2 screws at the bottom. Gently pull the entire trim that surrounds the stereo, cd changer and ac controls. You will now have access to removing the stereo. It's very easy after that. After you connect the wire harness and install the new stereo you need to run a wire from the red ACC wire on the stereo to the NBS relay in the fuse box under the hood. That's it! Good luck. Sorry I have no pictures.

Installing CD player


here is the wiring schematic.
Constant 12V+ Orange Switched 12V+ Yellow Ground Black Illumination Gray Dimmer Brown Antenna Right Window Trim Front Speakers 6 1/2" Doors Left Front (+) Tan Left Front (-) Gray Right Front (+) Light Green Right Front (-) Dark Green Rear Speakers 4" x 6" Side Pillar Left Rear (+) Brown Left Rear (-) Yellow Right Rear (+) Dark Blue Right Rear (-) Light Blue

And you will need a Wire harness... Metra #GMRC-LAN-01
And a mounting Kit Metra #99-3305
And antenna adapter Metra #40-cr10

This is for the basic radio... if you have upgrade NAV/Onstar/Premium sound.... there are different wiring harnesses available.

Let me know if you need more help.
