I'm currently using the middle red wire at the bottom of my plug that's plugged into my accelerator (tps, throttle position sensor). The plug has 6 wires, 3 up top and 3 on bottom. I used a multimeter and did get a reading of .4v with throttle at idle and 4.0v when throttle is completely pressed down. My issue is that I have a cruise control plugged in too and this wire I'm using is also piggy backed in to the cruise unit. I'm just not seeing any improvement with thus Steinbauer chip, I don't have an exhaust but I thought I would see some kind if improvement. What wire is everyone else using?
Cheers.
