I knew about the orange wire with 5v, but I also got 5 from the green wire. I had to use an engine ground because I got no reading from the black wire, however when I used the black wire as a ground to test a different connection, it worked there, just not on the TPS. Wierd huh? Anyways, the battery is disconnected and I'll post with KOEO results after an hour. From my wiring diagram, it seems that the orange wire is the "Fuel Sensor Ground." Where should that ground to?
