3.1 TO TPI?(EASILY DONE?)
IS IT POSSIBLE TO CHANGE A 3.1 HARNESS TO A TPI SETUP? LOOKS TO ME LIKE THE ONLY THING THAT NEEDS TO BE DONE IS ADD ANOTHER SET OF INJECTOR CONNECTORS TO THE EXISTING HARNESS.ANYONE DONE THIS?

I don't recall having heard of anyone doing that particular swap. I have a bud who did a V8 TBI to TPI harness mod, including re-pinning the ECM harness.
Most people just go get a TPI harness and are done with it. Much, much easier.
