Wiring up a Wego III. From searching, I found out to get RPM signal from on of the fuel injector wires but which wire? Does it matter? Also, I am going to get TPS signal from the Main Throttle Sensor which is a yellow/white wire pin 26 on the ECU. Next I was going to get my power from the ECU power point then ground out the WEGO unit at the ECUs ground.

That sound right?

I have an 07 ZX-10 US

Sounds good, you can pull it from the injector wire, basically all the injectors will have a positive and a negative wire, the injector gets a constant positive power and then the ECU will ground the negative side so you would tap into that, all the positive side injector wires will have the same color wire.

If you get to much noise you can tap the pulse wire of the coil as well.
