    ok, i've looked at wiring diagrams like crazy....but i can't figure this out. i have a 1987 project truck that originally had TBI(harness has a TON of connectors) and im about to cut all that crap out of there...but i can't figure out which wires i need to hook up the ignition, and to make the lights run.

    basically,out of the wires coming out of the fuse box(inside engine bay), which wire do i hook to the battery to give the fuse box power???

    and which do i hook to the starter so when i hit the key, it gives the starter power???

    the lights are still wired up, as is the oil pressure sender, and the temp sender. i pulled the ECM wires out since they were just getting in the way. i don't believe that i need them do i????


    thanks alot guys!

    My ignition wire to the starter in my 82 cab is purple (10 gauge wire i think). And I have two power wires into my fuse box (both red and 10 gauge i believe), I think one is supposed to come from the alternator but I have a high output one wire alternator and ran it straight to the battery.

    yup, 2 10 gauge feeds.. 1 from the alternator, the other from the starter, via the junction block on the firewall above your driverside valve cover...
