Over time and talking to our customers it became evident that we needed to develop a simple system for our customers, without a lot of electrical background, to install a second switch in the living space of the RV. Folks are beginning to understand the importance of keeping the gray valve closed and only open when the tank is 2/3rds full. Putting a second switch inside for the electric RV dump valve makes it simple to empty the tank with a push of a button after washing clothes or taking a shower.
We standardized on the Mate N Lock style 4 pin flat plugs many years ago.
Every valve we sell for use in RVs has this plug on the valve, unless the RV mfg. specifically ordered valves without them. We then offer a number of extension cables that plug into the valve and go to the operator switch wire harness so it is a simple matter of plugging each one together.
Here is a diagram that illustrates how everything plugs together.
