Engine wiring. Help please!!
My car was fitted with the mems 2 i think it is 1.6 k series. With only one ecu plug.
I now have a mems 3 vvc trophy engine going in and the ecu has 2 plugs, one of which as far as i understand goes to the cars loom and i have no idea how to wire this in.
Has anyone out there done this!?
