crank it on my wire harness i have 6 leads from the fuse block. (2) go to the hot sources and (4) go to ignition sources. i connected (2) to batt. and (4) to igniton sources that get power when the key is turn on. also my starter is wired to the old wires that powered the 383 starter. my motor turns over but wil not stay crunk(idle). the company that sold me my harness, computer, tac mod and pedal states that the tac mod is what keeping the motor from running. has anyone encounterd this situation?
