Hi everyone I need help! Can't find my fpcm looked behind rear seat under parcel shelf , stripped out boot found aerial booster (by jack) traced wiring of fuel pump , joins main loom. No fpcm .I must have one as i have the dropping resistor in the engine bay (alumunium box by turret)
I have a fault as the resistor gets very hot. Does anybody know where it is? The car is a 4dr r32 gtst

Here is a picture of where ive been told it is but nothing there . Nothing to indicate something was there.
 My car has been off the road for 2 years now and this is the only thing thats holding me up.
Please?

The resistor will get hot cause it's dropping the voltage of the pump. The earth for the pump runs through that resistor at idle and light load then gets switched to earth for full voltage. It's in the drivers side rear guard at the back, pretty much the same place as where that aerial amp was but on the drivers side

I did the hardwire fuel pump mod with 30 amp relay but am using the ecu switching wire to switch the relay on .  I suppose thats why the resistor is still connected. I want to bypass the fpcm . I'll take another look.
