my 2 biggest concerns are these:

Concern #1:
coming from the power fender harness there is a plug that doesn't match when I swapped dash boards to the 93 version without the passenger airbag. The wire colors look the same but the connector is different and the terminal size also seems to be different. I don't know what its for and if I need (or dont need) to splice in the old connector.

Connector from new(93) dash


(black) connector from original (95) dash


(helpful?) reference picture


I don't know if I need a different year of the FSM to find the connector and its purpose but I haven't seem to be able to find useful info about how to find which connector it is. The harness layout diagrams you can barely make out which connector is what and then tracing it back to what it plugs in to is also confusing. I need to get better at this.

Concern #2.
I used the bulk head harness from a donor car to send to iWire for my merge. 99% of everything plugs in the same and these are the ones left open on my old harness vs the donor(merged) harness.
I'm sure its fine but I would like to know what circuits they are in case I can use them to add in fog lights or even sunroof power.



red circle is original bulkhead harness and I think the top connector actually goes to the door harness and the black should be ABS (which I deleted anyway)

blue is the donor and I'd really just like to know the purpose of those 3 plugs that dont' have a home. I'm assuming one could be the ABS and maybe the other is the cruise? (also deleted)



So there you have it. I'm fairly certain none of this is show-stopping shit but for my own edification I'd like to know how to figure this shit out. lol

Any help is greatly appreciated.

Alright, this is actually harder than just tracing out the engine wiring diagrams, but I *think* the black one on the '95 harness is for the high beam indicator lamp on the cluster. If that's true, it's the F33 plug coming from the front of the car and the i6 socket/connector inside the car headed towards the gauge cluster. If your headlights are in and working you can probably turn on the high beams and then check for voltage across pin 3 & 5 (red and blue white).
Not sure the right way to cite the Subaru FSM, but the diagram is here

For the rest of them, can you get:
- a photo of each that clearly shows the number and arrangement of the pins
- a shot of the back with as many of the wire colors as possible

Maybe someone has a better way to reference this stuff, but that's what I tend to use when trying to positively ID connectors in the FSM.

I see. So you use the approximate location, then look at the connector shape/pin count and see if the wire colors match up and then can find it in the appropriate electrical section.

tedious but logical

here are the other ones:

I think I've seen this one referred to as the diagnostic connector




this guy, only one black wire


this is probably ABS or cruise?




this one i had on my old bulk harness too and was taped up away




this one was also unplugged in the car originally


and I got this new relay I didn't have before..

Not everything is used. The taped up one may be an accessory you did not have, like cruise control.
