Knock sensor, throttle sensor and engine speed. Rest are just power and grounds.

the wire colours are the same all the way from the ECU to the sensor, so find the coloured wire at the sensor plug and look for it on the ECU side. A pinout of the VSS/TPS plugs will give you what you need. I believe the Y4 does not have a knock sensor so you'll need to add one.
