Use the one closest to the plenum - opposite the throttle linkage. The other one is for the traction control. Use a multi meter and measure the voltages - the wire you want will have a voltage that ranges from .5volt to around 5volts when moving the throttle. Cheers
I have another question, For a fuel supply line can i use the high pressure line (by the brake booster) or should i drill and tap the rail or banjo (FPR) ?
