I'm hooking up a Greddy Ultimate on my ninety Supra. I'm looking for a wiring diagram for the E.C.U. harness, I need to know which color wire recieves which signal, R.P.M ground, power, A.F.M. timming, e.t.c. I know there's pin location chart, but, it would be a heck alot easier if it went by color instead if tracing down the wire to the pin location. Is there a diagram explaining which color wire recieves which signal?
