I wanted to add a switch to turn the fuel pump on and off in the s14 but, I am having trouble locating the fuse for the fuel pump. I looked on the fuse box cover and it is NOT written on top ( like the s13). I would appreciate any help i can get. Thanks

You don't put a switch on the power side, do the ECU trigger, black/pink just like every other Schassis. Found at the ECU, F3 plug, or the relay.

from what i was told by wiring specialties.....you got to follow a purple and black wire to the the ecu and the relay is on the driver side kick panel. so you can put switches there.

You were told wrong. There is no purple/black wire anywhere in the car.

I dont want to be "spoonfed" any answers but, Once i locate the black / pink wires do you have any suggestions about wiring the switch? I was planning on locating the fuse and running it like the diagram below.

if you want to do a switch on the fuse... it in the engine bay fuse box.
if you want to wire it from the ecu... its in the passenger side kick panel. black/pink wire.

i got that.

Do NOT put a switch at the fuse. NICO is fucking retarded, don't even begin to look through that shit.

The black/pink is a low current ground trigger so there's no need to fuse it. A SPST switch will do fine. Pull the relay, clip it the trigger wire, and run each side to the switch. Done and done.
