TPS Adapter Harness used to run a M50 TPS on a M20 engine harness. Commonly used with Megasquirt PNP ecu upgrades.

This product is a professionally made wiring harness allowing plug and play use of the TPS without modifying the stock engine wiring harness.

Can be made in a different length if you have special requirements. Default length is ~ 6″ which is perfect for a M20B25 install with stock Intake and Throttle Body.

Made with OEM TE-Connectivity Components and Motorsport grade wire. Made to order.

Alternatively the wires may be switched in the stock connector, however due to wire length and the inverted direction of the e36 TPS this puts strain on the harness and is not recommended.

The TPS needed is from a E36, PN 13631721456 (Not included)

Price increase for 2022 due to increased connector costs, my apologies!

The wiring may be modified by re-pinning the stock connector or via a short adapter harness. The adapter harness provides ease of install and lower risk. The stock wiring is brittle and oil soaked at this point, and the e36 TPS faces the wrong direction.
