To start the car was swapped to a 5 spd. It is a 92 daytona 3.0 5 spd. I am putting my new engine in and there were a few plugs that weren't connected to anything so I am wondering what they are for and what to do with them.
Picture 1: Old wiring that went to the auto's TCM Since it was swapped to 5-speed you don't have to worry about them. But the black connector has the reverse light wires in it, so if you want working reverse lights you have to wire them up to it. It also has the neutral start wire, it's the yellow/brown wire and should be connected to a ground.
Picture 2 is for the EGR. If your car doesn't have EGR leave it alone.
