I installed them on a buddy's Jeep. Check out the building of Meanst thread and there are pics.

Start looking around post 96.
Great Goes the switch lights (words) dim if you turn on the lights?
What wires did you tap into (colors)?
The words are illuminated when the headlights are on, and they dim with the rest of the dash lights if that is what you are asking. Honestly, I don't remember the color of the wire I tapped for the dimmer (might have been orange with a brown stripe or brown with an orange stripe.) It was a long time ago. I tapped the OEM cigarette lighter for the power to the switches. Keep in mind that the Jeep is an '08. Not sure what year yours is but I would google to find out the dimmer wire color if you have a '10 or newer.
On the 15, go the drivers side footwell light. Tap into the orange/grey wire for a dimmable power source for your switches. Extremely easy to do.
Nope, hot to orange/grey wire and black to ground. Orange/grey is a hot wire.
ok got it but the OTRTTW switches have 3 posts?
Hmmmm, not sure then. I have the OTRATTW 5 post switches
I would bet you use the Orange/grey connection as switch power, your ground and then 3rd post to your relay .
OP - What switch bodies do you have?
Here are wiring diagrams for the OTRATTW switch bodies.
