4DoorE30 11 Report post Posted July 31, 2015 (edited) HI guys, I pulled the m20b20 from my prefacelift '87 e30 today. I believe it is running L Jetronic. My new engine is from a 325i E30 which was Pre facelift aswell, however I think it was a motronic car and it did not come with the wiring harness. Both my ECU's have two rows of pins, however they are different sizes so wont connect up. Please correct me if Im wrong but I think I need a motronic 1.0 wiring harness and I will then need to change some of the wires in the c101 plug. Need the harness asap, Im in tauranga but am willing to pay for the harness and postage. Edited July 31, 2015 by 4DoorE30 Quote Share this post Link to post Share on other sites
