How difficult is the RB25DET to wire?
When I wired my car, I kept my 240SX interior harness (runs dash, headlights, tail lights, etc…) and got rid of the KA engine harness and ECU. I replaced that harness with the engine harness and ECU from the RB25DET. I then had to extend wires for the Gauge cluster and Ignition so that they would reach the LHD side of the car. I then integrated 5 wires from each of the harnesses ignition systems and made a power terminal where both harnesses were attached at the front of the car so that they would each receive power.
