Wanting to switch to 205/255/257 ignition coils in your 25D heads? This is the harness for you! 100% plug and play, replacing the factory ignition coil. Available for both styles of factory coil pack.
Note: this harness requires the Igniter on the firewall be deleted. Contact us through our contact page with the exact year/model of your vehicle, and we'll let you know what wires need spliced together.
The last two pictures are of the test harness built for proof on concept. The first four pictures reflect the completed products. These harnesses can be customized for full sequential or different coils upon request.
