I have switched the changed to obd1 distributor, injectors, gsr harness and p28 ecu. I was told that the gsr harness would plug right in but I am missing a plug on the gsr harness. the original harness in the car has a 6 wire plug that is with the main plugs by the battery. can anyone tell me what I have to do to make this work. thanks

 

yes gsr harness is plug n play. you will prob need to wire o2 to a 4 wire

 

the gsr harness is missing the 6 wire plug I also have a si harness and it is missing the same plug. it also so has a bunch of wires that dont plug into the motor. can anyone help me I have been struggling with this swap for over 6 month and have been told alot of different things. if anyone can tell me exactly what I need to it would be greatly appreaciated.
