1990 Legacy Turbo engine swap

[adam_r]

Hello to everyone. New here and looking for a little help.
I have a 1990 legacy wagon 2wd. I put in a 1992 turbo engine, car runs fast but my problem is its running rich.It won't pass emissions. It was a complete drop in I have the air flow meter and the ecu from the turbo car. The turbo A/F has 4 wires the original A/F has five wires. The ecu from the turbo will not make the car run but it was running in the old car. Does anybody have a wiring diagram for these cars? Has anybody done a swap like this before? any help would be appreciated
Thanks Adam

Also, there's been quite a few people that have performed that engine swap, so you may want to search around for some more info.

Was the 90 Legacy automatic or manual transmission?
