Cab Wiring access?

[KatahGii]

So I’m trying to trace wires from the fuel pump to the engine bay. And I noticed that it appears that the wires go into the floor of the cab. Does anyone know how to access these wires?

You have to take the seats out and pull up the carpet and you'll see where it goes.   While it's pulled up check for rust on the floorboards and get it repaired before it gets worse.

The harness runs along the rocker on the drivers side of the vehicle and up towards the fuse box. Just remove the drivers seat and pull up the carpet. There is also a connector just after the harness comes into the cab. There is another by the fusebox.
