Radio Illumination

[kfernald]

Thanks for the reply.

Unfortunately the boxster's radio harness plug was previously removed so I cant match the wires I have with their old locations in the plug. I was hoping to find a wiring diagram that showed me the color code of the particular wires.

I have obviously miss-wired something because when I turn on my headlights the head unit cycles erratically. I guess the most likely thing is the connection to the illumination sensor, but I don't know which wire that is. I think I must have something tied to it that should be ground and then when I turn on the headlights it goes high.

I sure wish the boxster's radio harness plug wasn't removed on the last radio install.
