If you are going minimal then take out the Porsche reverse logic FP relay and install one that turns on with ignition power (switch) via a relay and install a roll over switch to kill it should you end up in that situation so it kills the fuel delivery.
Ford ranger or bronco (or similar) tip over switch will work.
You can likely sell a lot of the harness pieces in the classifieds.
Or just send them to me to use some of the connectors for new ones.
