I have a 1991 Nissan Pathfinder/Terrano with Z24 petrol engine

Plan to add in a fuel pump cut-out hidden switch as an anti-theft measure. Anyone know where is the fuel pump relay ?

What about the related wire harness ? where would be the best location to cut the circuit for my hidden switch ?

Have done a search, but seems that none covers the fuel pump harness. Would be great if someone has the wiring details.

Any info available is very much appreciated.

I couldnt find any info on it either, Have you tried looking at the fusebox under the hood? There might be a relay for the fuel pump.

There is no fusebox found under the hood.

I did tried to take a look at the fusebox under the driver's meter panel. Not so easy to access those bunch of wires hiding underneath. A few relays were also found inside the panel next to the tail light. Not sure for what exact functions.

Open up the cover for the in-tank fuel pump. It has 4 wires connection there. 1 or 2 are used for the fuel gauge, i believe. Not sure it has single or dual flow rate pump. Any idea ?

Might need to spend a weekend searching for the right wires/relay if no information is readily available here.
