90 Accord with swapped F20b motor

I bought a 90 Accord with a f20b engine and there are some problems with it. Whoever did the swap didn't hook stuff up properly. They cut wires and left things unplugged. I'm wanting to fix this problem but don't know which wiring harness to get for this car. The vtec is also not hooked up. What components would be suggested to have for this?

Thanks!
