Throttle Postition Switch (TPS)

TPS
I chose to use the stock Toyota TPS. It is very easy to wire in and Haltech offers a way to calibrate the TPS to the E6k. These wire colors are for the 1991 engine. the wiring harness changed in 1993 and yours may vary. I know for a fact that the All-Trac harness is different.


WIRING NOTE To use the stock TPS
Stock Red/Blue goes to Haltech + / Orange wire
Stock White goes to Haltech Reference / White wire
Stock Pink (Cruise Control signal) N/C (I do not know if you need the pink wire connected)
Stock Brown goes to Haltech ground / Black wire
