I remember this was something I was going to do when my coils gave up, still havent tho.
IIRC there are pins A,B,C,D
A = Black, Ground
B = Brown, Reference low (ground this one also)
C = Different colors on each connector, (Ignition signal from ecu)
D = Pink, Power in (+12V)
I was going to ground Black wires at the coil mount and the Brown wires through the original coil grounds.
For the ignition signal wires, these are the wires that go to the ignitor from the ecu. You don't use the ignitor with LS1 coils!
