Multiple switches for water pump
My water pump currently has one on-off switch. I would like to be able to turn it on-off from several different spots on the TT. What would be the easiest way to accomplish this?

There are two ways..
One is to run a latching relay as someone up-thread suggested, This means replacing the switch with a 3=position switch, spring return to center, Depending on teh latching relay will determine the switch but a common one I know of you apply power one way to "CLOSE" and another way to "OPEN" This is the kind you need. This would require running 3 wire cable to each switch SPDT Spring return to center (ON)off(ON). switch. (The prens around (ON) mean momentary).
Option 2 is to use multi-way house switches, Basically the hookup is like this

Fuse---Switch #1======Switch#2======Switch#3====Last switch----Pump
Note the two wires between the switches
not also that though the 1st and last switches are common 3-way switches, teh two I put in the middle are hen's teath,, (hard to find) you may have to special order those.
