Ditto with killerformula.
What color are the wires you have on the distributor rite now?
You can make a test-light with a light bulb holding the wires on the bulb, or use a old socket. I believe its a double wire with one brown on the left as you are looking at it and should be hot with the key on. The hot plug wire goes on the the one nearest the cap, and can only go on one way as they have alignment tabs on the connectors.
The other wire should be the tack if you have one.
Luv the smell of NITRO in the morning.
