Trying to find this from the dealership or online is proving extremely difficult. i just need something to make 100% sure i have the right pins.

Thanks!!

Hi Richard.

i have been searching the web like a savage and i think i might have found the issue, of course tonight's test i think will confirm this.
The wires we went off is showing 5v when i tested it last night, this is pre-crank. so i'm expecting to see 5v on the voltage when doing the test tonight. i think the issue comes in that we used the power supply cable instead of the signal cable.

I'm not 100% sure if this ECU pinout is correct but from my understanding the voltage is the key here. i'm assuming if i can find out which wire shows the 1.7 to 2.4 Voltage and when idling the 1.1 to 1.6 voltage then that is the wire i need to trace back and connect to the control unit ECU harness.

This might also explain the constant on no matter what...?

What is the MPS trigger set to read voltage wise?

Thanks
Pierre
