Is it possible to add a 3rd brake light to the rear of my Big Country 3250TS ? I posed this question on rv net and was told it was not possible because of the way rv's are wired.....bummer...

Bob, for once RV.net was correct. If you just wired into one stop lamp wire....your 3rd stop lamp would blink when you turned on your T/S. I think Tom has something for you.

Well, it depends on how your GMC rear lights are configured.
I'm pretty sure that you have amber turn signals and red brake lights independant of each other. That's how my 07 GMC was.
If that's the case then you should be able to add a wire from a brake light on your truck to the third light that you are looking to install.
It will not blink.

Peace

My Big Country tail lights have 3 wires going to each light........a white, a black and a red....does any one know what function each performs??
