So I just got a new harness for my 1990 240sx with a blacktop sr. So I installed the harness and turned the key and the motor cranks but nothing turns on. I dont think my ecu is getting power. I looked at the old harness and the new harness where the big grey plug plugs into the main car harness it looks different like my old one has more wires then the newer harness from a 94 180. Is this my issue do I have to re pin the harness. Has anyone ever encountered this.
fixed had to convert harness
