High port to low port swap, wiring harness?

You need to use the highport distributor and ignitor.  You also want
to use the highport temp sensors and accessories (power steering
pump).  Then use the highport ECU harness and the highport fuel
injector harness.  Everything else is a swap over really.  This is
very straight forward.
