Wiring Specialties LS1 / Vortec Swap Wiring Harness for BMW E36 - PRO SERIES

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 the GM LS1 Cable Throttle engine swap. It was developed in house on an actual LS1 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.

Note: LS2 and up engines, additional accessories and other injector types are subject to additional fees.

CHASSIS: BMW E36

• Factory Speedometer functions by utilizing the ABS system outputs. As long as this system is properly functional, the speedometer will remain accurate.
  
• Factory Tachometer remains accurate unless number of cylinders changes. Use Dakota Digital SGi-8 if the number of cylinders has changed from factory.
• A/C wiring utilizes stock BMW fuse box AC relay and wiring. The AC compressor connector must be wired to the chassis’ output AC signal wire.
  
• Retains functional alternator charge light, reverse lights and wipers.
  
• Optional Factory Gauge Sensor Adapter is needed to retain the factory BMW Oil Pressure cluster functionality. The adapter is also machined to support most aftermarket temperature and pressure gauges that require a 1/8"-27 thread pitch. Will require the use of 1-wire OBD1 Oil Pressure Switch for E36 – BECK Part# 2011515.
  
• Use an OBD1 Coolant Switch from E36 – BOSCH Part# 02801300 for cluster engine temp functionality.
