So I want to know which wire goes to what there is a connection for trigger its connected but I dont know which wire colour for BAT and which one for TACH and how do I know if the rotor or module is working?

connection for trigger??? All you need to do is find which of the wires is hot to the old coil or distributor with the key on. It will be a thicker wire. This is really the only one you need for the car to RUN. Not sure on the tach, probably need some sort of adapter for it. Dont think the external coil distributors had a tach out but im not sure.Test it with a meter to see if your getting 12 volts with the key on. If you are then splice you a spade termial on there and plug it into the batt terminal on the distributor.
