They make kits just for this. Just plugs into the existing harness and then you run you wires to the wires from that harness, some may even have matching plugs that go directly to the Head units wire harness plug. I did My Mustang by cutting into the wire Harness and simply used a multimeter to check for battery, memory 12 volts and running light or dash board Illumination wires then you can test the wires coming out from the stock radio to see which are right, left , front, rear, antenna out, etc..
I just labeled them with magic marker on some masking tape with what they were before I cut off the harness permanently.
Most aftermarket pioneer cd/radio decks have the electrical connector for the antenna that I've seen.
Is this a cd only deck, or does it have radio functions?
Did you use a new harness wiring adapter to get the pioneer radio to work with the old harness?
There should be a color coded set of wires for the power antenna on that. And, then the Pioneer radio should have wires that were labeled for the power antenna.
DON'T TRY. REPLACE ALL CABLES BECAUSE IT WILL CAUSE ALTERNATOR NOISE ON YOUR CAR AUDIO SYSTEM- IT WAS SPECIFICALLY DESIGNED TO THE ORIGINAL SET AND DOESN'T WORK FINE WITH OTHER.
DO NOT ASK MY HOW I kNOW THIS
you need a wire harness for your car you can buy them at most auto parts stores make sure and buy the one for your make and model they should have instructions and the wiring diagram most harnesses are color coded and pretty simple to install
you will need to unscrew your dash and pull off the front plate of your dash, then you will need to unscrew the stock radio, then you will need to go ahead and pull out the adapter from the back of your radio. Next you will need to attach your adapter harness to your car harness and splice the color coded wires to the harness on your new cd player.After that, you will need to plug your antenna back into your new cd player, Note that some cd players will require an adapter, these can be found at circuit city or at your local car dealerships.-Shocker
first of all putting in non genuine stereos usually you have wires left check the fuse in back of stereo check all your fuses under your dash and in the bonnet even if wires touched momentarely its enough to blow multiple fuses which may be your problem your wiring may be fine see how you go
