Default 98 RS Tranny: Can U Identify These Wires?

I am installing a '98 Impreza manual transmission into a '92 Legacy turbo that was an automatic. Can anyone help me identify these wires? Are they neutral indicator? reverse lights? etc. ???



Thanks in Advance! For more details on my transmission swap project, check the following link.

I think...and this is only a guess.... that:
1 = ?
2 = Reverse Lights
3 = Rear O2 Sensor -I think the top part shown in your picture is where it plugs in [on an Impreza] to the main body harness. It should just run over the top of the tranny then down the drivers side, both wires should split, one going into the reverse light switch and the other going to a connector for the O2 sensor.

I'm not sure what those are specifically but I know from doing my 6MT swap the three things on both trannies are speed sensor, reverse lights and rear O2 extension. So those are likely the three plugs but I'm not sure which is which.

If you read the transmission forum often you would have know that 90-97 tranny are compatible while change had been made around 98.

I was comparing two wiring diagrams and it looks as if you could splice the correct wires together if you had a spair transmission harness.

I think the white connection labeled three is the rear 02 extension, which you could just remove.

Ciper: I choose a '98 Tranny instead of a '90-'97 because that is what I already had in my parts bin. Thanks for the advice. You really hit all the forums don't you!

Thanks for you input everyone. I forgot about the rear O2 sensor.. that clears things up.

So will you be running the 98 transmission using the 92 TCU? Im interested in your progress, as I plan to do the same. My reasoning is that I want to grab an auto from a forrester (4.44).
