I'm looking for some electrical help.
Here's the problem. I got a used electric antenna for my e28 only the circuit board has been removed and someone has directly wired the white and red plug directly to the positive and negative of the electric motor.
The way the antennas normally work is that there is 12V hot at all times running from the red wire and 12V when the radio is in the ON position running to the white white wire. There is a black wire for ground.
The antenna I have is simply two leads running to the electric motor. Put power to red and ground white, motor makes the antenna go up. Reverse the leads, put power to white and ground to red the antenna goes back down.
My question is, how can I wire up something which uses the factory connector and goes UP with the radio turned ON and goes back DOWN with the radio is turned OFF. This is the original intention of the antenna and what the circuit board that is no longer there did.
Here's a picture of my old antenna with a fried circuit board and the used one without the circuit board.
Using relays or something how can I wire something up so it goes up with the radio on and down with the radio off? Is it possible? I don't want to run an extra switch.
