Checked out a SR20, need help on identify couple problems

[dongoesby]

I have came across to a sale of S14 SR20DET swapped into a S14 Zenki 95'. My Car is S14 Kouki 98'. Here are my couple questions:

The S14 SR20 starts and runs smooth with steady idle. The major concern I'm having right now is the conversion of harness. As the harness are completely converted in this 95' Zenki, does that mean I don't have to do the harness work when I swap it to my 98' Kouki. If it would be interchangable, I would use its ECU which I might not need to convert anything.

Here are couple leakage pictures I took:

This is some oil leaking out from the tranny, possible worn gasket?
