any easy ways to take out the wiring harness of a TPI without cutting it and making a mess, i'm using no sensors or other wires except the starter wires and the ele. fans, which i'm going to wire up seperately

yep, unplug it from the ECM, then unplug everything under the hood that comes from the passengerside harness, then pull the rubber plug that insulates the wires from the sheetmetal at the rear of the passengerside front wheelwell, then pull the harness through that hole.
You might still have to cut just one or two wires. Don't forget to unplug the part of the harness that goes into the dash.

where is the rubber insulator

Between your firewall and the passengerside door hinge
