Anyone have copies of the EJ22 wiring schematics for a Legacy? I'm working on pulling the wiring harness, and the schematics in the EJ writeup are quite helpful, but still missing a lot - I'm trying to label and figure out what's what so I don't miss anything.

Also - if you need any parts off a 90 Legacy, let me know. You rock! Not trying to sound like an idiot here - I read through the conversion write-up - but where does the EJ22 harness get spliced into the EA82 harness?

I'm starting to feel like I bit off more than I can chew Strip the EJ harness down to just engine-control stuff, and then splice those wires in wherever you can grab them. Thanks for all your help so far! I need to get the harness pulled out completely I think before I can really make any sense of this!

I need the ignition and fuel pump relays, and the VSS, temp, and oil pressure wires. Its probably easier than I'm making it out to be, but whoa! I'm so confused Is it necessary to get the freshly machined flywheel, or can I make due with the old flywheel just grinding out the holes to match the EJ flywheel? Will putting a new clutch on the old flywheel surface be problematic in the long run? Looks good Chux, you are great at these write-ups! Can't wait to get mine going.

Is there a list of the "engine control stuff" anywhere? And also a handful of wires coming in from the middle of the firewall it looks like the cam angle sensor enters there - and some other stuff I've not dissected out yet - anyone know what a "dropping resistor" is and do I need to keep it? Basically, what needs to be kept beyond the wiring that obviously goes to the engine? Wires to splice into the gauges? Part of my troubles here are that I don't yet have real good diagrams to go off of I have a Haynes manual.

Numchux's digrams have been real helpful, but I can't tell if they are incomplete or I'm just dumb You need to be a member in order to leave a comment. Sign up for a new account in our community.
