I've been reading on the forum for a couple months now and have used some things I've found on here to do a couple mods on my truck and would like to give back a little bit.
I have a flip-down cup holder on the front instrument panel but no lights and finally decided to do something to make it easier to find my refreshing beverage at night. (Sorry, I didn't think right away to take pictures step-by-step... I think I have enough to get the idea across though.)
I took off my dash and unscrewed the cup holder mount. That was the easy part. I already had 5mm LED's and holders and because I'm cheap, that's what I used. I had to then figure out where I wanted to put the LED's so they would properly light up the correct area and not get in the way. Finally I figured out I was going to mount them towards the front of the cup holder in the portion that angled forward towards the dash.
As you can see, I decided to put in 2 LED's for each side of the cup holder. I should have taken a little more time and marked the position of the holes before I started drilling. You can see that they don't quite line up...
In the next picture you'll be able to see why this was a little stupid but in the end works out for me anyways. Now I popped off the front panel of the cup holder and realized I should have done that first...
You can see the arms that control the size of the cup holder will smash into the LED closest to them. Eventually I'm sure that will break the LED but for me, my cup fits perfectly without shrinking the size. Now you can see all my wiring and LED's are installed on the cup holder.
On the backside of the cup holder assembly (side closest to the front of the truck), you can see my wires sticking out. Be sure you leave a bit of slack in the wires for the opening and closing of the cup holder.
Now I needed a way to get power to the LED's. Cigar lighter happened to be the closest thing and, conveniently, is only powered while the keys are in the ignition. I spliced into that connector.
Well it was nice to have the lights automatically come on but I wanted to be able to flip them off when I didn't need them (Plus I plan on adding more LED's elsewhere) so now I needed to find a place for a switch. The open spot below the vent on center passenger side was perfect. In went the switch.
And of course the reassembly of the dash and cup holder installed.
And with the cup holder down.
Please excuse the mess... It was raining and I didn't feel like cleaning in the cold rain...
And finally pictures with the lights on. Sorry, don't have any taken at night yet...
And a closeup with them on.
I don't know if I missed anything but that's about all I have on this little mod. I need to do a little cleaning and then get some pictures in the dark because I'm sure you would like to see those as well.
