Pats is not hard its four wires.
Whats the code name on the ecu ? for a blacktop upto atleast 1999 you dont need the dash.
Ive done several from 92 pre pats eec-iv upto 99/2000 eec-v's

This is a 99 ecu that I wired for a guy. It is only a test and doesnt idle as it should as most of the sensors where sat on the car and not in the engine ....
