I replaced my radio on my 95 with a new Sony. Now the antenna goes up when I turn on the radio and down when I shut off the radio or turn off the key. But when I open the door to get out the antenna goes up again and in about ten seconds it goes back down. Lot of extra wear and tear on the antenna. Any one have a problem like that?

I would pull out the Sony and recheck the wiring. Aftermarket head units usually have two leads for powering 1. Antenna; 2. External amp. The only thing that comes to mind in your case is the possibility that somehow you didn't ground the radio properly or attached the antenna power on lead incorrectly. There is also a relay for the power antenna located under the rear hatch trim. If you had a Bose system, there is a relay (at least in my 89) that should be disconnected when swapping out the factory head unit for an aftermarket.

I can't agree with this. There are many people on this forum who have swapped out their original Bose receivers, and their antenna works exactly like it's supposed to, without making the motorized antenna non-functional. The pink wire from your receiver should be the wire with a problem. It should be hot (12 v.) only when both the ignition and the radio are on.

Perhaps my message was confusing so let me try again. I wanted to point out to the OP that there is a relay in the rear for the power antenna so he could check both the relay and the connections to it; and there is another relay (not related to the antenna) for the Bose amps located under the right side of the dash.That relay is discussed in the second video, When installing an aftermarket radio, it is suggested to disconnect the Bose relay to prevent battery drain since one is no longer powering the speaker amps. The pink wire you refer to is the factory power antenna wire that would work in conjunction with the OE head unit's pink wire and not found on an aftermarket head unit. The antenna control wire on aftermarket head units are usually blue or blue with a white stripe and all the ones I've seen have a small label attached to the wire indicating it's purpose. That wire should be connected to the coordinating antenna on wire in the cars harness. I'll look into my notes and post some pictures of the wiring diagrams for both the factory wiring and the aftermarket wiring.

Yep, your comment about the Bose relay confused me. The OP's complaint was about his antenna doing weird things, and the Bose relay doesn't have anything to do with that issue (as you rightly clarified). The Bose relay is controlled by that same pink "antenna relay actuation" wire, which is only hot when both the ignition and the radio are on, so it can't cause a "battery drain" problem either. If you unplug all four speaker amps, the Bose relay isn't doing anything.

All good friend!
