Does anyone know what the wiring for pin 15 goes to/does? The information I have shows it to be "Voltage supplied in Start"-(overload protected). I just hooked up a new Pioneer headunit with a wiring harness. However, the harness did not have wires for pin 5 (which I discovered to be the antenna booster), 18/19 which are for the steering wheel controls The harness has pin 1 (voltage supplied at all times- overload protected), pin 2 (Accesory delay relay switched output), ground and the -8- speakerwires (pins 8,9,10,11,12,21,22,23). So what function is pin 15 for? Is it only related to the factory radio? Everything seems to work fine. Any help would be appreciated as I want to make sure all items are present and accounted for. Thanks in advance for the info.

Yes, the unit turns on and works like the factory radio in the acc. and start positions and turns off after 10 mins. once the car is shut off.

I am not sure of the brand. I received it with the radio from Crutchfield. However, it did not have a lead for the "antenna power" (booster turn on) or for this pin 15 ( also nothing for the steering wheel controls, but that makes sense. I bought the Pac-Audio adapter to retain them.) I think it is just for some function of the factory radio.
