HEllo,
Hopefully someone here can help me. I'm needing to know what pins are what on this ign module, as I don't have the harness I'm going to have to make my own.
I can find plenty of circuit diagrams on the net, but need to know which pins exactly on the module.
Thankyou in advance for your help.

Hard to tell depends on the model its from ?

im not sure if your 4 pin plug has labels for ABCD or not, but:

A = EST Ouput = W = D4 on ECM
B = Bypass = T/B = D5
C = Dizzy Reference high = W/V = B5
D = Dizzy Reference Low = B/R = B3

All the diagrams i have show what colours go into the 6 pin plug but not what order, so im not sure how much more help i can be there, really need someone with a plug to take a phone and post up.

I can't see any ABCD on the 4 pin plug anywhere. But on the 6 pin plug there are some numbers as can be seen in the pic.

the far right wire goes to injector power, it also goes to the coil power and its 15 in that picture

On my MSD I used the tach signal.
