    Here's a little project I'm working on. Most of it's done now that I have the wiring figured out. Not the prettiest job but it'll get cleaned up after I get the light bar mounted. I wanted to find a switch that would fit the blank next to the factory Off Road Lamps button. Couldn't find one that didn't look goofy. I wanted a stock appearance and the switches with curves and bumps and stuff just didn't sit right with me. So I did some research and the nice fellows at Titan Talk had completed something similar using our Off Road Lamps button. So I bought one. And then pooped myself trying to figure out what to do next.

    The switch has 6 pins on the back and is a momentary switch; it doesn't latch...Just creates a short to activate the lights. To simplify, the 6 pins are actually 3 pairs - top 2 create the short to activate the lights, middle two are for the illumination and the last 2 are for the orange 'lights on' indicator LED.

    Here are some pics of my process:

    You can see my initial notes are incorrect. This one stumped me a little bit.

    Inserted pins and then used 5-minute epoxy to secure them in place.

    I dig the look...

    Always keep your fuses close to the source!

    Bosch relay fits perfectly in the relay box.

    Here's what I used instead of a latching relay. The latching relay was $25, in the UK with a $25 shipping charge. Nope. This little gem does the same thing and is $16.

    Strapped down.

    My initial kit...The old latching relay thing is 5V, so I have a 12V to 5V converter. Bought the 12V version because I didn't want to have an additional failure point.

    Here is what I wired up:

    Now I just have to mount the LED bar in the mouth and run the power wire. Positive lead connects to the same lead of the relay that is connected to the Lamp On Indicator of the switch. Negative to ground. Then it's done!
