I am seeking the 55 pinout on a 1.3 motronic harness for an 179 ECU that I wish to piggyback with my Haltech ECU.
The wiring I have on my OEM ECU starts with Pin 1 = Red/White, Pin 2 = Red, Pin 3 = Brown/Black, Pin 4 = Brown/Blue, Pin 5 = brown/Grey, Pin 6 = Empty, Pin 7 Empty, Pin 8 = Yellow, Pin 9 = Black, and Pin 10 is Empty. Is there any 55 pinouts that represent these first 10 wires? Please contact with whatever information you may know, so that I can proceed with this undertaking.
I have a question about my dash lights. Sometimes when I turn on my lights at night the lights for the air con controls light up and sometimes they don't light up until I hit a speed bump or something. Is it just the lights I the dash or do I need to fix some circuitry?
Hello everyone... My BMW 525i isn't getting any power to the fuel pump fuse I have changed the fuel filter already but when I did that the fuel fuse went out can someone please tell me what I should do?
Thinking about purchasing a 1995 530i, car seems to have an electrical issue. Something about the passenger side window. Is this an easy or inexpensive fix?
