TPS Problem
 

I have the FM II installed in a 90 and since I installed it I've had problems pick up the tps signal on my laptop when I try to calibrate it. I know the tps on my car is an on off type. I figured something was wrong with it so I bought a vtps off the BMW 5 series. When it showed up I installed it and had the same problem. I got volts going in and I get volts coming out the signal wire at the tps so I traced the wire back to the car harness and I get volts there. Thats when I notice there is no wire coming off the Hydra harness at that location. What gives? So I checked the wiring schematics for the car and it show the signal wire as a red wire with black stripe but mine is light green with white stripe like the 94' and up. So short story long, does anyone know where on the Hydra's harness is the signal wire located? Thanks for any help.

Jeremy at FM e-mailed me the instructions. Problem solved. Mods can close thread
