Lighted Water Pump Switch

It's generally a best practice to shut off the water pump when you don't need it, because if you have a leak or a break, the pump will keep running and fill your van with water. However, the factory 'One Place' switch for the water pump is inconvenient, so we tend not to use it.

Jim Lincoln, from the Revel Facebook group, found instructions for installing a simple, lighted momentary switch in the Travato group, and he wrote up some better instructions for the installation. A simplified wiring diagram is here. I'm including all of that, along with photos from my installation.

Here are the tools and materials that you need.

The switch comes with a short harness, so I soldered about 4 feet more to each lead.

I started with the electrical work before cutting a hole in the cabinet, just in case things went south and I couldn't complete the project for some reason. Here I spliced in the leads according to the instruction guide. The extra leads in the Battery and Ground terminals are for the after market water gauge that I installed a year or so ago.

I spliced a 1 amp fuse into the power line, then covered the splice with heat shrink tubing.

I used some adhesive clips to route the wires safely behind the drawers.

I installed some bullet connectors inline to shorten the wires and give myself a quick disconnect in the future.

I used a 3/4" spade bit to drill the hole through the cabinet.

Works well, and is a lot more convenient to use.

Water Gauge Replacement (Loeza Method)

(Note: This is one of several methods of installing the Topargee water gauge in the Revel. See here and here and here for others.)

This what I did, no drilling needed. Just made the pipe, then slid it underneath the existing plumbing without removing the panel, then just made the two connections.  Tightened connection at winterizing valve first, then at pump.  This is the same hose you guys put the flow meter on, the hose from the winterizing valve to the inlet of the water pump (suction side).  It took 30 to 45 minutes to do.  I tied into power and ground at the switch for the running board light.

The special order fitting from Home Depot is this one.
