Description
Looking for the best in aesthetics, weight savings and reliability out of your harness? Our Pro Series harness completely replaces your old OEM harness so you can forget about those electrical gremlins.
This Wiring Specialties PRO Series harness was designed from the ground-up to exceed OEM specifications for wire quality, power/ground routing. With our optimized and ‘tucked’ approach the end result will be a clean and worry free installation with a guaranteed start up.
This Universal Harness is perfect for Race / Track cars, cars running a stripped interior / switch panel, or classic pre-EFI cars with the GM LS1 Cable Throttle engine swap. It was developed in house on an actual LS1 engine to ensure a perfect fit to all engine connections.
Wiring Specialties offers a number of options for common performance upgrades for this product. Build your perfect harness by selecting from the available options to the right, and as always – if you have any questions, please reach out to us.
Note: LS2 and up engines, additional accessories and other injector types are subject to additional fees.
