Hi everyone. I new to the site.
My 85s power antenna is broken. I replaced it with a new factory one. The old one was aftermarket so some of the factory wires were cut and spliced. I'm trying to figure out how to wire it. I have been searching the archives but didn't come across anything useful.
I have contacted the dealer but they don't have any wiring diagrams that old.

I am hoping some one here could point me in the right direction. Or a picture of a none modified harness would be very helpful.

Thanks in advance.

I did an aftermarket antenna in my 83. This link was super helpful:

Antenna Replacement

For you specific question, make sure to read the bit about grabbing power from the trunk light and the bit about the wiring in the plug that used to go to the OEM antenna.

Upshot: you grab one of the wires from the factory plug (blue and blue yellow I *think*) and use that to trigger the up/down on your new antenna.

 

Thank you.
The repair manual helped alot. there were only 2 wires i had to fix and remove jumpers at the relay connector under the dash. with out the manual i would not have thought to look for that relay in the front of the car.
thanks again.
