Ok guys i want to have a crack at my megajolt tonight.

i have sussed out everything other than the pins on the TPS sensor and crank position sensor.

the crank position sensor i believe is ford and has 3 pins on it marked 1 to 3. im guessing 2 are for signal and one is the shield but am not sure which is which

the throttle position sensor is off the zx6r carbs and also has three pins of unknown designation.

any help would be great as i dont fancy frying components

TPS:

quote:
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 MegaSquirt® 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, then disconnected wire is the one which goes to ground, the other one which had the continuous resistance goes to the +5 Vref from the MegaSquirt® EFI Controller, and the remaining wire is the TPS sense wire.

I can confirm that method of testing works with zx6 carbs

cheers flack thats really helpful. didn't think of looking at the megasquirt info as i only have megajolt but is now quite obvious

second question does anyone know where i can get the plug that connects to the zx6r tps as i don't have one and it doesn't look like a standard plug

I never managed to find one and just used little spade connectors. No probs so far.
