Will any manual starter work? I think I'll just get one from the WRX.

Obviously, it has to come from a manual.

Smoke no, the manual starter has to come from the proper phase engine (phase I or phase II which ever it may be) and the starter must be the same style clutch also, push/pull, myself and sleepy subie are on the sneeking suspicion these are quite similar but haven't definite proof, if you have a WRX pull type starter then by all means see if it lines up with the push type flywheel and report back.

Voluo5, I've found that the ECU's neednt be changed. remove the TCU unit from the RS and leave ECU's alone.

Youre probably not going to have ABS after everything is done, and I still don't have any reverse lights after the procedure either, but id still like to know what is involved in getting them to work..

If you're interested in ABS check the links I posted in the beginning of the thread.

As for reverse lights mine work fine :P I'll post pictures since the car's interior is still stripped down.

anyone done an OBD1 5mt trans swap into an OBD1 auto ecu impreza.

just wondering what the wiring will be like for my swap. I've got a 92 turbo legacy trans/linkage/drive-line w hydro clutch going into a 95 impreza with a turbo kit on a ej18 running the stock ecu which is for the ej18 and auto trans

Going back and updating everything to be easier to understand. till then this is the most straight forward way of explaining the simple method for making your car road legal with a manual transmission.

Wiring is theoretical but consists of the following splices

1 to state a false neutral (bridge the signal for a real neutral switch)
- The shifter has 4 wires going into it two control the shift lock mechanism (just a simple solenoid) the other two are a switch to let the ecu know the engine is in neutral Splice these two

1 to ignite the reverse lights (two wires spliced to two other wires, non polar)
1 to deliver the neutral signal (two wires spliced to two other wires, non polar)
-On 93-01 Impreza Transmissions These plugs are separate from each other on 02+ Imprezas (non sti) these are a single plug. on the WRX you will need to get the wiring diagram to discern which is which. you need to splice these into the plugs that would normally go to the automatic transmission.

You will have to do your own wiring diagram research as the transmission and car harnesses vary from year to year.
