Zazzn,
I'm trying to hook up a Greddy Ultimate
Do you know where I can get information on a wiring diagram for the harness for the e.c.u. on a "90" Supra? I would like to know what color wire recieves which signal, instead of pin location, I think it's easier by color than by pin location. I have an old H.K.S. F con (black box) I'd like to cut off the H.K.S. Plug and splice in the Greddy harness
Thanks!!!
