The reason im asking about it is because Mr Kawasaki done a strange thing, the wiring is set up on the original motorcycle that with a CLOSED throttle the 5V reference reads 5V & with an OPEN throttle this drops to near 0V, so it's in reverse.To hook up your throttle position sensor (TPS), disconnect the TPS, and use a digital multi-meter. Switch it to measure resistance. The resistance between two of the connections will stay the same when the throttle is moved. Find those two - one will be the +5 Vref and the other a ground. The third is the sense wire to the MicroSquirt® controller. To figure out which wire is the +5 Vref and which is the ground, connect your meter to one of those two connections and the other to the TPS sense connection.
If you read a high resistance which gets lower as you open the throttle, the disconnected wire is the one which goes to ground, the other one which had the continuous resistance goes to the +5 Vref from the MicroSquirt® EFI Controller, and the remaining wire is the TPS sense wire
I used my multimeter (set to 20k-Ohm) & found the 2 pegs which didn't vary. I then followed the instructions to find 'Ground' which left the sensor wire to uS.
When i connected my red lead from the multimeter to the sensor wire & opened the throttle the reading went from 1.9 to 3.9, am i getting it correct that the sensor wire will then read close to the 0V with a closed throttle & then up to 5V when it is opened?
