I have several questions:
· What is the port on the upper right-hand corner used for?
· Is it a required hook-up?
· I notice d the hook-ups for the eight peg plugs, crank sensor, and vacuum hose.
· Does anyone have model that can replace it?
· Can I replace it with one that does not have a port on the upper left hand corner, but does have the eight peg plugs?
