Too many wires with car stereo installation Sign In

Trying to install a Pioneer DEH-33HD car stereo system in a 2005 Chevrolet Trailblazer. There are too many wires left over when you hook the system up. What are these wires for and are they suppose to connect to anything? Thanks!

The info should tell you what wires are what. I'm guessing you have a power antenna and an amplifier signal wire hanging loose. Please tell me you are using a wiring adapter for this and not cutting the factory harness up.

Too many wires left over on which end? What color are the wires that are left over?

Getting the wiring adaptor tomorrow. Will that take care of the "extra" wires? I had to go on the internet to find out what wires went where. No info in other parts. Thanks!

Wires are left over from the harness end, but we are getting a wire adaptor tomorrow. Will this fix that problem? Thanks!

Don't know. Do you have the Bose system? With or without navigation? One of those wires is going to be a data bus wire that you sure don't want to short or connect to anything.

It does talk to me like when my Ipod is low on battery. It also scrolls the station, etc across the screen.

No. All controls are up front on the radio.

Re: Too many wires with car stereo installation Sign In

This radio is going to be a little hard to wire up because you'll have to run an accessory on power wire to connect to the red wire on your new radio.

The stock radio has one power wire that is hot all the time that feeds it and doesn't use another wire for accessory power.

The radio you want to install should have a yellow and red wire. The yellow would get connected to the orange wire in the vehicle harness. You'll have to run a fused accessory on wire that is hot when the ignition is on to the red wire on your radio.

The black wire gets connected to the black/white wire.

Blue/white wire doesn't go to anything and should be covered unless you are using it to turn on an amp or plan on using a power antenna.

LF speaker
White to tan
White/black to gray

RF speaker
Gray to light green
Gray/black to dark green

LR speaker
Green to brown
Green/black to yellow

RR speaker
Violet to dark blue
Violet/black to light blue


The other wires you have to fold and heat shrink and tie up, so they don't chaff on anything.

I suggest that you solder and heat shrink your wiring unless you can find a radio harness adapter.

Steering wheel controls won't work. You'll probably see a trouble code in the BCM for the radio because the bus isn't connected. You won't have automatic volume control or hear any warning chimes. Other features may not function, so you may want to check that out.

If you want the warning chimes and on star to work with your aftermarket radio, you'll need to buy an integration adapter.
