Dash plug wiring help - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I would really appreciate some help. I have a 1990 240 that originally had a SOHC ka24 and auto tranny. I replace the KA with a early redtop sr and 5 speed swap. The issue I have is the dash plug. There is the original little white plug above the ECU and the one that was on there does not match the wire colors on the sr harness. If anyone has a diagram with the colors or knows what color wire match to the sr harness that would be greatly appreciated.

The single cam dash plug is different and won't plug into the SR dash plug. Cut off the plug pigtail on the single cam ECU harness and wire that to the SR, or go find a plug pigtail on the dash side on a twin cam and wire that onto the dash harness.

Go find a single cam FSM and match wires to the ECU dash plug. Search my posts.

Thanks I appreciate it but this is for a DOHC KA24, not the SOHC.
These are the wire colors on this white plug:

Black
White/Blue
Yellow/Red
Green/Black
Blue
Yellow/White
Green/Red
Yellow/Green
