Jake, thanks for posting the photos from the FSM. May I ask where you found the FSM? I keep getting weird factory manuals online, like Hayne's types of manuals. I can't find anything that has the plugs labeled like yours. So again, thank you for posting these, and could you help me find the copy you have?

Also, my only comment on the upper radiator support is this... The upper radiator support gets the axe 9 times out of 10 with v-mount setups. These cars generally see much more chassis deflection up front under load than our street cars ever would dream of, due to what they are typically being used for. For this reason, I believe that chopping the radiator support is not only a fair option, it is a great option.

Way to make me want to fiddle with the 00' again... Thanks.

Here you go everyone. Keep checking this post, as I will update the image as my swap project continues.

 

[Jake]

I can chime in with your uncertainty in some of those, if you want.

 

[Taiden]

Would be helpful, Thanks Jake.

the ecu doesn't care about the neutral switch or parking switch. Nor the ps fluid level switch.
the backup power is for constant 12v to keep the learned revision tables stored on the rom.

B62 - 4: Not sure how you got the AACV tied to it?

Air flow sensor Vs should be B61 - 11, not B60 - 11, at least as per the wiring from the FSM I have.

Side note - the Recirc Gas Temp is California only. I was looking high and low for it on my engine before I found that in the FSM!

Otherwise, this looks pretty solid.

Any Hydra users can give me a shout for a pinout sheet... They're tough to come by sometimes!

B61 - 11 is not populated on my wiring harness
B62 - 4 traces to the AACV on the wiring diagram

I have found my fair share of errors in FSMs over the years, so unless you have the harness in front of you, it's kind of pointless.

Are you sure that every year has the same pin out and wire colors?

At least from what I have researched with impreza ECU wiring they are quite different throughout the years.

Yeh, the 1992 SVX manual wiring diagram doesn't always show the same colors as my 1992 SVX harness.

 

[Jake]

92-95 is all the same, for sure. except for the egr.

I use an oem book, I have never had one wiring error or issue. I've done a dozen of these...

Done the dash switches?

 

[Jake]

define dash switch

define dash switch

Cruise, fog, rear defog, hazard, security.

 

[Jake]

for the svx? I don't do anything FOR the svx, I just gut them :lol:
for the rs, everything you mentioned but the cruise is untouched.

Take my word, there are parts of the wiring harness in the SVX that don't match their documentation!

 

[Jake]

don't doubt it by any means, I'm just stating that entirety of the wiring from the 4 plugs to the engine harness are perfect (from my oem book)

They can't be that different, as the ECU had no changes.

 

[LetItSnow]

...entirety of the wiring from the 4 plugs to the engine harness are perfect (from my oem book)

Well, at least they got some of it right!

 

[Taiden]

The wiring diagram is accurate, but the pinout guide is sketchy at times. That's why I put up info from both on my OBD1 svx swap diagram. [[info in brackets]] is from tracing the diagram, other info is from the pinout guide.

I am going to be doing some work on the OBD1 swap diagram tonight, i'll post up the modified diagram. I haven't had to touch wiring for a while, so it's been sitting stagnant.
