okay I have a few minutes to spare, So an explanation of my intentions to get this thing running on the OEM ECU.
The immobilizer on the legacy is integral to the body integrated unit that powers all sorts of things like, doors, lights, security pretty much everything. I figured it might be easier to make my forester think it is a Legacy by swapping over the bulkhead wiring harness, which among other things would give me a nice updated interior and modern controls of the a/c-heat radio etc. So grabbed some legacy interior parts to check if it even fits close enough to be usable. On to the pics
The legacy dash fits suprisingly well a couple small issues but good enough for me for now
Heater box fits as well, just need to cut new holes for the heater core pipes and the ac lines
new holes cut
and the wiring fits pretty good too
the wiring was quite a project in itself, I merged all my rear wiring with legacy bulkhead, just alot of staring at diagrams, staring at wiring, wondering why i thought this would be easy. lol
