Like the title says, I just bought an M90 with L Jet to put in my Bavaria. Can anybody advise me on what wires go where? Any help appreciated.

Thanks in advance.
 
Depends on year of harness. Early harness is two piece. Upper harness is for injectors and lower for spark. You can leave in your old distributor and use injectors or you can install the whole system. There is a wire that needs to be connected to switched power by the coil for the injector ecu to work.
You will need to integrate the wires for switched power, constant power, water temp, oil pressure, fuel pump, alternator, tach and starter.
 
Thanks Don. From my research, the only hard parts I need to switch out are the oil pan and pickup? And I will need to install an electric fuel pump. Anything else?

Thanks,

Allan
