Auto to manual wiring - 94 BG5 Legacy

[Guest]

Hey all,

Yes i have tried to search for the answer but couldnt find what i was looking for :-[

Have a BG5 legacy, its a 94. Motor and box out of a 96 GT legacy. How do i go about wiring up the manual box, some answers i found said just snip one earth wire, others said a whole lot of things had to be done.

Any help appreciated

Thanks Scott

Not quite as simple as snipping one wire. Reversing lights are easy to hook up. Neutral switch will need a relay if you want to use it and you may decide to change to a manual ECU as well. You'l also need to change to a manual ABS computer to do the job properly.

Im using an auto ABS unit in my manual conversion and it isnt good.

Mainly after info regarding the neutral switch, can you shed a bit more light on this? do the computers just straight swap? Cheers for the help

Not sure on engine computers swapping, have never done it on a BG. ABS should plug straight in with no rewiring needed.

If youre going to use the Auto computer you will need to hook up a simple relay to reverse the throw of the neutral switch. In the auto trans, closed switch is neutral and open is in gear. Manuals are the other way around.

Without the neutral switch you'll get a funny idle and possibly stalling at traffic lights.

Also Youll need to wire the speed sensor into the auto trans loom. Simple enough with the correct wiring diagram.

So if use a manual computer will i still need to run the neutral switch?

Forgive me if i dont sound like i know what im talking about im a mechanic just havent had alot to do with subarus!

Im 90% sure youll need to run one. Only takes a $10 relay so its not a big mission. Id wait for someone elso to confirm as ive only done BC and BH conversions

Just thought as well - your exhaust wont fit quite right, the hangers on the Auto are in a different place to the manual. I fixed this with a big hammer on my wagon but you might need to look at finding a manual front section to get it to fit profesionally

Ok will see what other people say, im not to fussed about the exhaust customers changed the box himself just can get it to run so brought it into me. Cheers for that though ill let him know

[Guest]

Surely theirs more people out there that have done this conversion that could help me out a bit lol?

Not much point in that as 99% of it is the same.

This link might help ya mate. Its for USDM BC/BF models but most of the stuff crosses over. Maybe some different pins in the wiring but the same sorta stuff.
