Orange wire problem - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Under my dash where the ECU is your supposed to connect the wires for the tach and speedo and the ignition. The ignition is my main problem. I have an orange wire coming off my SR wiring harness (its supposed to be for ignition) but nothing off the KA harness to connect it to, I mean no orange wire that connects to it.
The problem my car is having is it will turn over and will start and run ONLY when i prime it with gas in the intake manifold. I am pretty sure that my injectors are not firing. I bought a new CAS ECU and wiring harness and new fuel filter and my fuel pump is putting out more then enough PSI.

I have a 1990 240SX with a redtop

Orange is the start signal. There should be one in the dash plug to connect to.
