just picked up a CRX with a b16 swapped into it with some issues. Firstly, the oil pressure sensor is not connected, and the sensor plugged looks like it was ripped off somehow, and i was curious on the price for one of these sensors.

the people that swapped in the b16 did a crappy job too, and weren't able to do the wiring with the proper ecu, which i have in my possession (bar code serial number: 37820-PR3-003), and kept running the CRX Si ecu that came with the car. And for this i need to wire the vtec knock sensor wiring, what is entailed with this if i connect the right ecu up and do the wiring at the same time, and what other wires should i be looking for while i am doing this? Any help would be great.
