alright thank the whole site any only 1 person know how to wire the thing ?

warric_k

ok, the red wire doesn't really go to a switch and +12V, it should go to the wire going to the distributor/coil that is ignition(most likely a black w/yellow stripe wire. the white wire from the msd should go to the trigger wire, which should be white/blue. the black/yellow is considered the positive side of the "coil", and the white/blue the negative.

I hope that helps. if it doesn't, let me know and I'll take pictures of whatever I can.

yeah we start it up but the rpm doesn't work and it seem like it doesn't run right late timing or something ahhhhh

warric_k

you tapped into the trigger wire right? you didn't cut it off completely?

double check your connections.. there shouldn't be anything hidden.

tell me which wires you've hooked up to what (colours and names).
