Hi, Hope you are still around to answer questions. I'm working on adding power assist to my 69 MGB GT. Based on your list I picked up a unit from a 2008 Nissan Versa. Unfortunately, I did not get the wiring harness (and custom plugs). So I have a wire 4-pin male 'out' pigtail from the torques sensor, and an 18-pin male 'input' on the ECU. Wires from the Torque sensor are Black, Red, Yellow & white. Do you know which goes where?
