should have a solid black that goes to a good chassie ground or i prefer to ground to the battery directly.should have 2 wires to the coil and 2 to the dist.they say that the dist wires go a certain way but it will run fine either way.


here is link to on line instructions

heavy red - batt postive

heavy black- batt ground

small black-neg coil

orange- pos coil

small red- 12 volt key source

purple - pos on dist

green-- neg on dist

if you have a msd dist the dist wires should have a connector like the box and just plug up unless some one chopped it off

got all that right i think its the ground at the dizzy or the 12v switch power

[Silver91Hatch]

The dizzy is grounded to the block via the hold down. Use a test light to see if you are getting power to the MSD.

are you running the 2wire billet msd dist or something else?

[badluckpony]

stock 3 wire dist.. but i dont have the black wire hooked anywhere

[Silver91Hatch]

What stock 3 wire dizzy?? Whats the part number or vehicle it came from.?.?.?

[nastynotchback1]

purple goes to orange dist wire

green goes to purple dist wire

black on dist not used

small red goes to what would be the pos coil wire which is a 12volt switch source

orange goes to pos coil

black goes to neg coil

white is not used.tape it up or heat shrink the end of the wire so it will not ground out on anything

[badluckpony]

done that. its a stock dist for a 85 302... batt is on charge try again later
