I'm just in the process of making a stand alone EJ22T harness out of the stock components but I'm a little hung up on some of the leads on one connector.

I've separated the engine/ecu related stuff from the chassis harness, and bypassed the SMJ's. Yes, I'm going to do something with the power supply and yes, I need VSS etc... yadda yadda...



I'm using the 1992 FSM as a reference and working on a '94 turbo harness.

But, after the cutting and soldering, I'm stuck at the E2/F26 Connector. What do pins 7, 9 and 10 do?


Pin 7: Jurisdiction ID goes to c11 (B56.11) No prob.
Pin 9: ???
Pin 10???

One I belive is oil pressure, but the other? It would be nice to figure this out via bbs, instead of voltmeter and prodding around the manifold.

Thanks for the help! I'm trying to get ready for our local rally-x, and swapping my drive train into this old impreza L.

I have the 91 FSM but I'm sure they are the same.

Pin 9: Oil Pressure switch
Pin 10: Thermometer

Have fun making the harness

P.S.
Are you sure where Pin 7 is going? I could be wrong but the schematic looks like it goes to b1 on the control unit Connector B58? c11 looks like it goes to a ground. Just thought I double check on that for you.

The '92 FSM scan shows F26.7 going F45.P6 to C11(B56.11) for calif. But otherwise maybe its just grounded. I just want to be bang on with this harness. I dont have much time for messing about frying ecu's.

B58.1 is my TPS ground uncut or un modified by me. I believe you have mistaken F26.2 for F26.7. The next wire down is the one I'm curious about. I

Please forward any other scans you may have to Brucebeveridge@gmail.com.

Thanks for the HELP! This is not fun. Making drift is fun. In a roundabout way I guess this will lead to making drift.

I went ahead and downloaded the 92 FSM and they are different. I see why you couldn't find the other pins too (The pdf is missing pages :C ) Anyways my scanner is on the fritz so I have to use my camera once I find it. But I'll take a picture of both pages so you can see what I mean.

The images have been sent. They are 2.4 Mb a piece (Hi Res). Hope it helps.

YESSSSSSSSS!

This is the information I needed!

F26.7 to GND
F26.9 Oil Pressure to dash
F26.10 Thermometer to ECU also to dash.

Excellent. You've been a great help.

These answered all my questions. Thanks to all.

Just wanted to let everyone know that these schematics came out of 1991 Service Manual Section 6 Issued October 1990 A. The PDF for the 92 shows different for the E2 and F26 connector. Please verify with a multimeter if your vehicle isn't one of these years. I don't want anyone to fry their ECU's
