If it doesn’t then you’ll know it’s the component itself causing a short not the wiring.

Hey fryzia, thanks for the reply!
Regarding the relay, in the PCS and PG sections of the FSM, there is not mention of the ECU relay being accessible. As far as I know it's internal to the IPDM, and may even be soldered to the board.
If the relay is inaccessible, I'll do a test on one of the sensors to see how well the voltage is doing. It was in range according to the ECU over OBD.
For the disconnected components, any recommendations as to what is less likely to harm the car? When I thought about doing this before, I chickened out because I thought I'd build too much pressure in the EVAP system without the EVAP Canister Vent Control Valve or the EVAP Purge solenoid, among other equally absurd reasons.
