Question location of some sensors on the MY02 factory ecu harness. . .

Hey guys, I'm installing my HKS CAMP system this weekend and I need to know which wires going into the factory ECU are for the speedo, tachometer, and injector duty cycle sensors. Constant 12V power (for memory) and power on ignition would be nice as well, so I can keep from running wires all over the place.

I have instructions for the CAMP, but it's all in Japanese so it's somewhat difficult to discern which wire goes where. I figured out which wire is which coming from the unit, but I'm not sure about the ones on the Subaru ECU.

Thanks!

JD

I had a better one that was color coded and everything but it is on my other hard drive that is partially crashed.. maybe I can recover it. We'll see. But this chart works just as good.

There isn't a "injector duty cycle sensor." I assume you mean the CAMP will compute injector duty cycle if you give it one of the injector driver lines, which are grounded by the ECU to turn the injector on?

Yup sorry, poor wording. From what I can tell the CAMP unit makes the duty cycle computation based on user-provided injector characteristics and an offset or multiplier based on the voltage range from the ecu.
