I am currently converting my 1996 Integra GSR which was down graded from a GSR to a LS engine ( I did not do it). Now I am converting it back, here is a list of what I have:

B18B1 LS engine with all OBD1 Wiring, even interior.
OBD1 to OBD2A conversion harness.
OBD2 Engine Wiring Harness.
Crank Sensor
OBD2 Catalic Converter with O2 sensor.
P75-A52 ECU
OBD2 Data link connector

I know I need a 1996 oil pump for the crank sensor but is there anything else I may need before I send it to the mechanic?
