I had no luck with search, so here is the problem, hopefully someone has run into this before.

I have 2 cars that should be the same, Car #1 2002 Impreza ts, VIN: JF1GG65542G812998, Build date: 07/01, Car #2 2002 Impreza ts, VIN: JF1GG65532G831414, Build date 02/02

Car #1 has ~ 220,000 Km (136,000 mi) and is in better mechanical condition but too much rust to be put on the road.

Car #2 has ~ 320,000 Km (199,000 mi) and has much less rust but leaks oil like a sieve. 

So I put the the 2.5L engine from Car #1 into car # 2 but the engine wiring harness on the engine does not match up to the harness on the body, anybody know why the difference and how to connect it up?

 

Thanks in advance.

Probably federal vs California emissions. Just swap the intake manifolds.

You might also need to swap the crank and lhs cam sprocket/gear for ignition timing to work properly or at all.

Thanks guys, swapped the intake and got it running, now have a different problem so will start another thread.
