Lou how difficult was this?
Not very. As with all my "simple jobs" it was harder than I thought. My 15 minute job took about 2 hours.
And did you have to run any new wires?
Yes, I used 14Ga double speaker wire (silver/Gold) to run power from the switch to the Vent. I used that because I had a 250 foot roll and no idea what to do with it!
I found the item on eBay NEW RV CAMPER 12V POWER VENT BATH LIGHT WALL SWITCH ON | eBay
That was the vendor. fast shipping with no issues.
Is it a matter of separating existing fan and light wires in the existing switch and connecting them to the new one then I can handle that.
Well, here is the deal. There is a single run of switched power to the fan shroud and a junction that then routes power to the fan; ceiling light fixture and vanity lights. I made a jumper that went from the "Lights" lug to the "Fan" lug. I tied the grounds together in the wall. Then I ran a new wire to the fan shroud and it was not all that hard to fish.
I used the existing run to pull the new run and a heavy string into the shroud. I untied the new run and pulled the existing run back into the switch box with the string. The lights switch now powers the ceiling lights and vanity lights. The fan switch just powers the fan.
I "could" be talked into taking the shroud apart and pulling the wall plate for photos, but not looking forward to it.
Did you have to enlarge the hole in the wall to accommodate the new switch?
Yes. The wall is very thin and cuts easily with a box cutter. (or even scissors)
