I am repowering a 1987 4.3l with thunderbolt ignition, to a 97 5.7l with thunderbolt, does anyone know how i could go about wiring the ignition on the 5.7, using the 4.3 wiring harness?
not sure what your asking but if using standard coils, purple and grey from the harness to the + and - coil and the purple and grey from the module to the coil + and -
