No power to fuel pump after motor / harness swap

Isn't the fuel pump wiring (relay and resistor box) on the body harness? What happenes when you jumper the yellow connector on the passenger shock tower and turn the key to the ON position?

*Just so it gets said* The fuel pump doesn't run until the car is cranking (unless you jumper the connector)

Fuel pump power goes from battery to fuse block under hood to main relay...
Yes, it goes through the other harness, and it has nothing to do with the engine harness, EXCEPT...

All Zenki FC's run a fuel pump cut out switch inside the AFM.
There's a jumper that normal sits right about the passenger side shock tower.
Easy way to test is to jump that plug.

It's in the FSM.
