if you are talking about the coil pack to the igniter then i think i can help. i had to re wire mine after the previous owner i bought it from hacked them up and didnt even bother to connect them. but here i think this could help, sorry colors dont match coming off coilpack but the igniter does, you should be able to follow it pretty easy. hope this helps i made it with a pic i found on ebay lol.

Just look at the wires. There's a white, and a tan one. The one that goes to all three packs is the 12 volt wire. You don't have to cut anything, just look at where the sheathing ends on the wire to the coils.
so theres a total of four wires comming from the green plug. One is 12v thats splits off three ways for the coils and then theres 3 ground wires for each coil. Right?
which one is the 12v source, the white or the tan?

my wires werent matching when i bought the car and the plug was gone i got a diagram from a tech and matched them to the coilpack myself..but i think its the tan ones i know the orange and black is the hot one and the rest im sure are grounds. i dunno im still new to supras.
Yes, the Tan colored (split 3 ways) wire is the +12V supply for the coils, but that is only on the coil side. its black with orange tracer on the harness side.
Take a look at this link.
