I have a new Alpine stereo all wired in (1991 Celica convertible). I bypassed the factory amplifier under seat using the amp wiring & the dash radio wiring (quite a harness to make up). It sounds great except no power antenna !!! I have the alpine aerial power wire hooked to the factory aerial wire (B+) but no luck. I've spent many, many hours trying to resolve this issue without any luck. I think there is another wire that has to be powered up also due to my meager internet findings. Please help if you have a clue.
Thanks,
