NOTE: This pin-in harness set is intended for use to add our high-power IGN-1A coil harness sets to a MPFI or distributor-based engine harness that was not originally intended for coil-on-plug. Since our coil harness sets have an external supply for power and ground, the power and ground circuits are blocked off and not included with this harness.
If you're looking to convert an MPFI harness to run factory-style smart coils, such as an LS D510C, D585, factory 2023+ Godzilla, etc, check out our pin-in harness with integrated power and ground circuits here.
Pre-terminated harness for adding coil-on-plug wiring into an ECU harness not originally set up for it.
