Need help guys: what wires to the coils???

The car is an 80 SA

The wiring seems to be different from my 81

I got the positives figured out, but I dont know about the negatives.

I took a couple of pics.





I have ONE green with a yellow stripe and TWO yellow with a green stripe.

What do I connect? why do I have 3 cables???


Thanks in advance guys!

thats one of the wires from coil to igniters.

thin yellow/green or blue stripe: coil -
thick black wire: coil +

I cant remember if its trailing or leading but its not hard to figure out. trace it from the igniters

Let me see if I have any shots in the bukkit...

This is the best I've got already uploaded:





I think you can make out the colors if you zoom in.

The third wire is your tach pickup. Goes to your lead coil negative. On an original 80 harness, the plastic connectors are color coded; blue clip is trailing (-), black clips are leading (-). The rubber cover for the positive wires are color-coded the same, but they're in fact parallel; swapping them doesn't do anything.

By wire color, that's black w/white to positive, blue w/yellow to Trail neg, yellow w/green to Lead neg.
