I just put a Pioneer DEH-P590iB in a 91 bmw 850i
I have attached pictures from the manual as well as a picture of the wiring harness. My battery died and i'm worried its because I wired the harness wrong. The car has a factory amp and originally when I wired the harness I did not connect the blue/white wire from the Pioneer harness to the BMW harness because there was only a solid blue wire left after I connected the rest of them.
I was getting the radio to power up but no sound. So I then connected the blue wire that says Power amp + to the blue/white which is the connect to system control terminal of the power amp wire on the pioneer. Could this be causing the batter to drain because I read this in the manual.
This is what I found for the wiring on the 850
The following numbers correspond to the harness that plugs into the BMW radio. Each wire has a number that routes to a certain location.
Documentation came from a 1994 manual pertaining to a BMW 8 HiFi 10 speaker system. I would double check wiring by using a light tester.
Radio
Pin#
1 = Speaker LF+
2 = RF+
3 = LR+
4 = Telephone Transceiver
5 = Accessory Power
6 = RR+
7 =
8 = LF-
9 = Battery
10= Body Electronics Module
11= RF-
12= LR-
13= Light Switch
14= RR-
15= Ground
16= Antenna Amplifier
17=
18=
19=
