Im mid engine swap from a 97 2.3 to a 94 3.0 and I have a small concern looking at my firewall over towards the brake booster on the drivers side. There is a plug the consists of three square plugs that I believe is my OBD2 system. Although I am not sure
The engine harness I have that came with the motor when I bought it has a round plug the is in the same place on the vehicle this came off of
I don't know if I need to plug it in for the vehicle to run properly as I've never taken on a task like this
Any advice would be great
I have access to the vehicle I bought engine from still.
