Project HCR32 GTST

Bought it a week ago as is, and apparently this thing has scene some drifting days.  
however I am aiming to get it to as stock as possible. 
 
fuel pump wiring looks it was bridged for some mode, the two (ylw n red) where chopped of the harness,  I want to know which goes where and if that doesn’t make the fuel pump go what was done to it ?

Yellow was connected to external  Red 

External  Black - slotted into factory connector 

red (factory loom) was unused 

External Black was live 12v with ignition 

both the other end of this black/red wire had spade connectors on it, as it was connected to something,

Please refer the photo attached,

Thanks

I have checked my fuel pump goes, if even turn on if that black cable coming out of connector is directly given 12v.

So yea fuel pump is all good.

Someone might have added an additional relay. Sometimes a relay is added to ensure a good solid voltage supply to the pump, or to by-pass the Fuel Pump Control Module (FPCM).

The two heavier gauge wires will be the power and earth for the pump, while the two smaller gauge wires will be for the fuel level sender (fuel gauge).

In the case of bypassing the fpcm, do you need make any changes to wire going to fpcm or to ecu ?

The FPCM drops the voltage to the fuel pump at idle, to quieten operation, and restores the voltage to normal as soon as the throttle is applied, so yes. Try to trace the wiring back, or upload some more photos. Judging from the single photo posted, the battery has been relocated to the boot?
