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 harness is specifically engineered for a BMW E36 (92-99) with any GM Generation IV LS Engine using an LS1 Drive-by-Cable Throttle Body, TPS, Alternator & LS1 PCM. This harness was developed in house on an actual Gen IV engine in an E36 chassis 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.
