Hello all of you who have successfully swapped the old stereo with a new, actually functioning one! I have recently purchased an '88 Vert, and am having some difficulty identifying the wires. I have read the wiring diagram, but am unable to decipher what it means. So to help, can anyone tell me what colour wires go into my new deck? Current wires on deck are:

Red (Ignition)
Blue (Power Antenna)
Black (Ground)
Yellow (Memory Back-up)

Could someone please help me with which ones from my harness I should connect?

Thanks!

 

Do not cut or tap into the factory harness. Buy the appropriate connecter from you local audio shop.

The manual for the headunit will list which colors are what and the aftermarket harness(see photo)should list what colors are which.



Hope that may help.

Thanks for the reply - I did buy a harness, but I have a spare Orange wire on the car side, not the deck side, and could only locate the ground by doing a voltage test, and hooking to a wire that was white with a stripe, as it had no power...but don't like testing like that. Anyone else run into this?

 

yeah, the stock witing is all weird.
I ended up only using the power, ignition, and ground from the wiring harness I purchased at the stereo shop. I swapped out the old stock speakers with some aftermarket ones so I ran the speaker wires from the stereo directly to the speakers. The reason I did that was to bypass the small stock amps located behind each speaker that would make the new stereo sound like crap. If you run into problems with the power antenna not working I know why. The wire in the dash coming from the car, that you would connect to the back of the stereo to opereate the antenna, needs to get a ground signal not a 12+ signal like the stereo is sending out. To fix this you need to use a standard relay that you can find at any autoparts store. Igf you can't figure out how to get the antenna to work still send me a pm, I can send you some more detailed info and pix. Good Luck
