At least there's no pink wires in a mitsu like there is in a GM harness...

There are exactly 5 wiring connections to make on a starion into mitsu swap. Constant 12v, ign 12v, start 12v, harness ground, fuel pump, and the common grounds. You need the spark box and the starion coil. The rest is bolt in and plumbing.

And I got 20mpg at 70 lots of times, on a crappy 85Starquest system. It's the blasts to 90 to pass the "slow til you try to pass" a-holes that kill you, and the WAOT runs to humiliate the ricers and the 'stangs, and all the times you nudge into the throttle just to hear the turbo spool up. Turbo 2dr Mitsu's sound like wheeEEEEEEEEEE. AND I could run it on 87 octane if I stayed out of a LOT of WAOT throttle.

The main benefit is the ability to climb grades without a downshift, especially in an a/t truck with the big gap from 4-3 because of the long legged overdrive 4th. I could o/d cruise at 80 on the I'state in hilly country and never downshift on 31's.
