Has anyone done a 5 speed swap on an early model 1st gen Forester?

Let me explain the situation. I have 2 complete cars, a 98 and a 99, The 98 was wrecked at 140k and has a fresh clutch, TB/HGs done, and was an awesome little driver. I picked up a 99 automatics for 500, clean body just a worn out drivetrain. Mechanically I’m perfectly able to do this, I 5 speed swapped my dads BMW E30.

My main question is this, the only solid information I can find for the electrical portion of this swap pertains to legacy’s/outbacks and similar model year Imprezas. I know all the mechanical things, we need the manual rear diff, radiator etc.

We were planning on swapping the cluster and ECU from the wrecked car, the new one doesn’t have cruise so we weren’t even gonna bother with it. It’s imperative to get this done with no check engine light as I live in PA and that’s an annual inspection issue.

If anyone has done this I would love to chat. Thank you so much!!
