RV With The Tanners Put A Master Light Switch In Their Bighorn's Bathroom

Melinda asked me during our last trip, "Why do we always have to flip on 3 light switches in the bathroom? Why can't it be just one switch"? After thinking about her questions for just a split second....I said, "You're right. Great Idea!"

In the photo above you can see my solution: a master switch installed about the three existing switches.

I'm sure there's a good reason for all these switches in the bathroom, perhaps to conserve power while boondocking, but we didn't really need that. So here is how I modified our Heartland Bighorn to put all the switches on a single master switch:

1 - Disconnect all power....both 12v and 120v

2 - Located the main 12v line, that feeds the 3 switches via a loop. (mine was a red/white wire)

3 - Cut hole for new switch and splice the main 12v line.

4 - Attached main 12v line to the master switch. (Link to Master Switch from Amazon)

5 - Screwed switch into wall....Done.

We can now leave the 3 switches in "on" position and turn them all on with the master switch. If we ever want to turn off a individual light, we just simply use original switch.
