K..trying my best here...looking at my 87 supra electrica wiring diagram book
from ignition S/W "IG2" is a black with orange stripe goes to a wire that connects the Igntion coil and igniter which is the same as the number one wire is part A (I made up the part a,b,c to sepereate them)
PART A
i show 4 wires between the Ignition coil and igniter
1. black w/orange stripe
2. light blue w/red stripe
3. light blue w/yellow stripe
4. yellow
PART B
1 wire from igniter to check connector is black
PART C
4 wires from igniter to ECU
1.light green
2. light green w/black stripe
3. light blue w/black stripe
4. light blue w/ white stripe
these are all the wires that touch the Ignition coil and igniter according to my diagram.
I wish i could draw a pic but i suck at it or scan it somehow...let me see what else i can do...gotta make dinner 1st for my daughter...
