I have finished stripping the EJ22t ECU and engine related wires from the rest of the chassis harness and I have 2 left over wires that I need to ID.

This is a 1992 Turbo Legacy wiring harness w/an automatic transmission. The wires are coming from connector F26, the 12 pin gray connector that connects to the engine near the driver side intake manifold. I am using a copy of the wiring diagrams from the Mitchell on demand program and a scanned copy of the FSM from 1992.

The wires in question are #9 (white-green) and #10 (green-white). I cannot find any reference to these two wires at all.

Anyone know where these go?

Also, is there a difference between an automatic tranny ECU and a 5spd ECU? If yes, do I need to do something with the neutral switch signal?

Other than that things are going well on the swap.

I'm not near my diagrams, but those sound like the wires for the water temp gauge and oil pressure idiot light.....just off the top of my head. have you accounted for those yet?

 

 

ECUs are the same. When I suspected my ECU (came out of a '92 FWD 4EAT Legacy), I plugged it into my dad's '94 AWD 5MT Legacy. it worked just fine.

 

you don't need to do anything with the neutral switch wire. it'll just assume it's in gear. might throw a code....but it'll work fine.

Yep.. looks like those are it...

THANKS:banana:

EJ22 ECU's are not the same.

 

But EJ22T ECU's are. MT and AT used the same ECU for the T's.

are you running a 22t engine as well for the swap? the 22t ECU is pretty versatile. that's what I'm running in my 97 OBW with a destroked/turbo'd ej25....
