I would like to add something...a wiring harness is close to impossible to screw up and I'll tell you why...say you cut a very important power or sensor wire off right at the harness, cause you thought it was a/c or cruise control, so you can't splice a new wire? Just push the pin out of the harness and replace. Just make sure to know the ecu pins well so you don't accidentally give something 12v that isn't supposed to.
You can in theory use pins to hardwire the ecu directly to the intake manifold connectors, and eliminate the connector (as well as ALL the original wiring) completely, it just happens that the factory wiring is very nice. Plus the ecu fits nice in the glove box.
Repinning the harness will allow you to mix and match ecus and harnesses when using obd2.
Just food for thought, or in case you can't find a running donor car right away...plieadies tends to line these things up for those with patience, and who help others.
Subaru swap life hack: buy a daily with ej whatever if you can for cheap. For while the loyale is under the knife.
I got a 92 leggo in addition to the donor. How else would I know you can Scandinavian flick an L body, but the awd leggo won't? Not even with the e brake! Plus a future engine after finding awd weaknesses lol! Don't use the handbrake for flicking the loyale, especially to the left, so flicking right. I'm sure you already know why. I flick my xt on the street cuz turbo...have fun with the ea82 But don't break it if you can help it...someone will want that engine and might even pay you believe it or not. I got $125 for my old carby ea82, that was the asking price too.
Save the rubber grommet cause it fits perfect on the firewall. And if obd1 (90-94 legacy, 96 and older impreza) do not remove the brown double diode on the alternator pigtail. It's critical.
