AUNI-200-USB Audio Mod for 88 535i Stock Radio

Post by Glennzbimmer »

I need help identifying where to splice in the 3 wired connector supplied with the Universal RDS USB.
The 1988 535i factory radio antenna "Euro" adapter kit supplied with the unit is installed correctly, now all I need to do is find the perfect and appropriate place to splice in ground, (black wire) +12V (yellow wire) and Ignition wire (red) so the unit turns on and off while turning the ignition on/off.

So, with the factory radio pulled out of the console and the glove box curtain lifted, there are plenty of wires. Can someone please recommend what wiring diagram I can use in the Bentley manual or can someone tell me the perfect place to hook this up? Pictures with locations and even wire identification numbers would be very helpful. Perhaps the power antenna connection would be a great source since it gets juice when you turn the car/radio on?

I'd download the proper ETM for your car from this site: http://wedophones.com/BMWManualsLead.htm

If your car has the auxiliary fuse box I'd run the power for your module from it, if not I'd tap the proper wires near the steering column connectors.
