Engine swap, need help fast...
I am swaping from a 2.8 MPFI to a L98 TPI. I have a painless wiring harness for the engine and the correct ecm. Do I need to run any wires from the drivers side to the ecm? I pulled the motor and tranny, saw all the wires that run across the fire wall (after I separated a lot of them between engine harness and other) I am just confused at the amount of wires still going from the drivers side to the ecm. PLEASE HELP ME!!!!

At a minimum you will have your ALDL, SES light, and other gauge wires.
