ECU number translation/harness


 

I am buying a new harness because it seems I have multiple shorts in the harness on the motor section between grey plug and sensor plugs. I have sourced several on the internet but seems like I should be using the ECU numbers to match with the harness. Can anyone tell me which numbers on the ECU correspond to match a harness ?

2000 Impreza 2.5L SOHC auto trans I think because yrs ago we did ground the parking brake wire. The number on ECU which I think is what I should use is : 22611 AF581. Other (all) numbers on ECU include (from top to bottom, left to right) M2, 22611 AF581, A18-000 DY5 9823.

The closest matching harness is 24020 AF531. So any guru advice out there on how to match up my ECU with a stock internet harness ?
I tried iWire.com but they wont build a custom harness even though they have all the plugs and wire. I am also open to other wire loom shops or ideas.

Also, I think Smallcar will create a harness from scratch.?

Your number indicates a 00-01 Impreza using Google. If from an auto trans, I think? you could comb the wreckers for another harness including 02 since they are all similar. Check the pinouts for each year. They are all the same.
