HELP! Radio PIN Connections HELP!

[acura_dude]

Somebody please HELP!!! I need a diagram of the PIN connection on the back of the Radio, NOT the color of the wires. The Radio has 1 big connector with 17 PINS and 1 small connector. Any pics or information on what each PIN is for will Help. Thanks

haha, you're lucky. I have a bunch of frayed wires. -_-

Mine is the standard BMW radio, and only has one slot-type connector. It's the tape/radio type. E30 318i Saloon.

If it's likely to be it, I'll fish it out and photograph the top of the radio, which has got a wiring diagram (although i imagine you've already got that).

All I can remember is dark blue is ariel signal lead (+12 and ignition = up, 0 = down)
