Antenna wires? Options

[yellowchinaman]

Im trying tk wire a booster antenna and it requires a 12v supply.
The stock antenna has a plug to the motor with 5 wires.
Which one of them is the 12v which powers the motor?

If you turn the plug to face you, it has a U shape. If I remember right, it's the two wires on the left side, one is constant and one is switched. I can't remember the wire colors at the moment but I'll walk outside and check in a little bit.

much appreciated Rich.
This is the plug.
I didn't want to constantly power the antenna. Only when the radio is switched on so it would be the controlled 12V I'd be looking for.

Our wire colors are different but the plug looks the same. Holding my plug the same way yours is, it would be my top right wire that is switched power. On my plug, it's sort of a tan/gray wire but on yours, the wire looks like a regular gray. The wire color may be different between our plugs but I can't imagine Toyota used a completely different antenna or wiring schematics between an ST204 and ST205.

Any time. I just happened to be messing with my window mounted antenna so it was still semi fresh on my mind, plus I happened to be out cruising around in the Celica for the first time in a while so it wasn't hard to check.
