I am trying to put the engine from a 90 Legacy MT AWD into a 92 AT
2WD. The main wiring harness from the engines are different. The 90 has 3 connectors while the 92 has only 2.
Can I modify the harness? Where do I get the wiring diagrams? Alldata or do I need to buy the Subaru factory manual?
Or could I swap out the intake manifolds too and hopefully use the old harness (it seems to be connected to the manifold, injectors and various sensors.)?
Any advice greatly appreciated!
