Finishing up m/t swap

[bvh56]

Im just finishing up the a/t to m/t swap in my 90 legacy. I was wondering if i could just take the park/neutral switch from the auto trans and plug it into the harness and place it into the park posistion so i could start the car and drive it around like that. I did remove the auto tcu and im using a 1991 m/t ecu that came with the transmission i bought. At this time im not worried about reverse lights or the cruise control.

All you have to do is jumper pins 11 & 12 together of the B15 AT connector, and it'll start up.

I'd suggest doing that until you can put a starter interlock relay in.....assuming you're going to do that.

ok ill give it a shot. Is the connector marked with that number on it?

[Legacy777]

No,

It's the 12 pin AT transmission connector in the engine bay that was connected to the auto trans.

There are images of what the connector looks like in my swap write-up.

I'm planning on doing this on my '93 ss. Do I need to find a M/T ECU? or does does jumping trhe connectors solve that? I have been told both.

ECU's are the same between MT and AT...all you have to do is clip one wire (ECU ID)

Use your current ECU. Swapping to a MT ECU, especially with the 90-91 MY's will cause you a bit of headaches.
