So i'm in the process of swaping out my automatic out of my 90 240sx, and putting in a 5speed from a 93 240sx le, and i was wondering if anyone has done this before? See the problem is i have a different wiring harness that is used in my car, and the 5 speed is way different! IE: some pigtails have a male end, and the old wiring harness has a female ends on it instead!, also the wiring harnesses have different color wires, and some with either more or less wires, with different guage wires! And i can't seem to located the neutral switch wire that would be necessary for the 5 speed. if anyone has ideas or suggestion that would be appreciated!
