Hi 56fire
what kind after market system are you working any model # ?

[56fire]

Holly TBI it's a older system a friend of mine got off of E Bay, but he didn't get a wiring diagram with it
it has a Purple wire, and a Red , also a Gray plus a Pink. I know the pink goes to the Coil and the black goes to
ground I think the Red goes to ing, power for the fuel pump but the other 2? any help would be great.
Thanks .
