Ok here another one and all switches and buttons from either me or someone else should be available to anyone wanting to change their burned out bulbs or switch to LED's. I will compile all threads into the Electrical FAQ section and include the infamous 7216 bulb number Mccall! :D

Items Needed:
- (2) 5mm LED's (preferably 360* viewing angle)
- (2) Resistors
- Small screwdriver
- Soldering gun and solder

First take your dash bezel off by pulling it out after you stick the truck in gear 1 and set emergency brake. Set it aside. Now take small screwdriver and pop out the tabs holding the switch in. Disconnect the harness. Now you should just have the switch by itself. Split the cases by releasing the tabs on all sides and top and bottom.

Now take apart and set cover aside. Take out clear acrylic light diffuser and set aside. Now you can see the bulbs. One on top and one on bottom.

Now turn upside down and reference where the bulb would be on the backside. Since this is a closed case meaning you cant take the circuit board out you will need to use the soldering gun to make holes on the back side of the case to get to the contact points. Just make sure you dont hit the circuit board while doing this. Its not hard. Smells like shit but not hard :D

Now carefully unsolder the bulbs. Now you can use a volt meter or a "test" led to figure out the polarity. Take it back out to the truck and plug it in and see which side of where the bulbs were is the = and which is the - and make note. The resistor always goes on the positive side along with the longer leg of the LED (anode). The sorter is always the anode or the negative side. LEDs are polarity sensitive meaning they only light one way. Now when mocking these up on the board make sure you take into account that the diffuser will have to set down on top of the board and not hit any wires or resistors. Just test fit first before you solder all together. Once you got it right then solder it up and put the diffuser on. Take it out to the truck and make sure it lights before putting cases back together.

If all checks out good then go aheead and carefully put switch back together and put back into truck. Button up the bezel and remember your parking brake is on ;) Heres my wonderful camera's take on it :rolleyes:

I didnt change the little 3mm lights on there as I wanted it to stay that color so it doesnt all blend together. If you want to then just figure out the voltage to see what size resistor you need and the rest is basically the same.
