I think it might be time for you to invest in a workshop manual such as that published by Bently. This will contain enough info for you to troubleshoot a range of electrical issues as well as others.

Boost Junky 1 Report post Posted October 8, 2007 Yea the Bentley manual i have been told also. Im currently making my wiring loom for my M50 in my E30 and there is a plug under my dash that i have to run a wire too im sure one of those two plugs are the one. Have asked on bimmerforums and r3vlimited to find out what they are for mate. Will let you know if i do find out, im pretty sure the 2 wire plug is your air conditioning one Luke Quote Share this post Link to post Share on other sites

There should be two other wires on that harness, 3 in total. Could you find out for me if have got the info still mate? Im also after the pinouts for the E30 ecu and the E34 ecu, best bet is to buy the Bentley manual dude im not in desperate need of them as i think the car will start.
