Yes, a standard Motronic 1.3 loom for M20 engines should have the one connector you need, next to the ECU plug.

so any e30 m20 engine loom can be used? I mean all m20 engine loom has an extra connector to control the engine speed if the air conditioning turn on, this extra connector is near the ecu plug.

is it correct?

or there are 2 different engine loom? with extra connector near the ecu plug and without?
