Richie-Van-GTi 71 2 Cars Posted July 23, 2007 need to know which wire is which on my R1 potentiometer (throttle pos), Ive hunted down the wiring schematics but it only makes clear which the signal wire is. It has 3 wires, blu, black and yellow. yellow is definatley signal as its the only one that is independant and runs direct to the ECU. The other 2 look to be inter linked with other wires and sensors so Im guessing they are positive and negative. Will it matter which way around they go?

Sandy 191 Posted July 24, 2007 Whichever one the signal "goes to" (least resistance) at full throttle, is +5v; the other is signal ground. Share this post Link to post Share on other sites
