Short movie from the startup yesterday: (save as) [.MOV (24 MB)]
We removed everything related to the diagnostic connector and kept just some of the wires that went to the chassis connector (ignition, rpm, alternator, starter, oil pressure switch, cluster coolant temp, ..).
We then basically rewired most of the cable related to the Motronic harness - the injectors to get sequential firing and all the sensors because we made all new grounds and didn't want the signal wires to be cut short when connecting the Econoseal connectors of the VEMS Genboard. We did re-use all of the trigger cable and connectors! We didn't re-use the stock injector miniterm connectors, we got new ones from the VEMS webshop which are easier to disengage.
All in all I think me and Stefan spent about 4-5 evenings on the wiring, this could've been cut a lot shorter if we had done it before and knew how the stock harness was interconnected..
We re-used the "cable box" that encases the injector connectors. Very neat after we zip tied everything and closed it up.
Glory shot of the car.
