![]() ![]() The leg without the resistor can be soldered through a hole in the switch. All you need to do is get the LED to be roughly aimed forward. Keep track which side of the LED has a flat spot on it (this is the negative side of the LED). Start by opening up the switch by prying the tabs on all corners of the switch carefully and separating the face switch from the body ( not necessary for headlight switch).įor the regular style switches it may be easier to solder the resistor to one leg of the LED ( anode or positive side is used for this tutorial). ![]() Current (A) = Resistance (Ω)įor this tutorial, I will be using 1.24K Ω as a resistor value. Now with the LED on, take down the voltage that you read on the power supply ( this is your LED forward voltage). Make sure not to violate the maximum current of the LED! Hook the LED up to a constant current power supply set at 12V so that you can dial in the appropriate current level so the LEDs match the lamps in the rest of the car. These pin numbers are written next to the pins on the back of the switch. Pin 2 on the switch is 12V and Pin 5 is GND. This step involves powering a non-LED switch on the bench from 12V and using another switch with the bulb removed from it so you can poke a LED through the back of it.

Lastly, I hot glued all around the tweeter housing. After the capacitor was in place, I cleaned up the solder. I simply tacked one of the leads (left photo) then moved on to the other lead. I found it best to hold the capacitor with my left hand and the soldering iron with my right hand. Now after selecting the new capacitor the pins need to be bent so that they can be soldered onto the existing leads of the tweeter.Īt this point, I tried holding the capacitor with helping hands but that did not allow enough room to get the soldering iron in. Be careful doing this and make sure to leave as much of the existing leads as possible.Īfter removing the rear speakers, in some cases the plastic holding the tweeter may appear cracked or the plastic may begin to crack after reaching a tool in to cut the old capacitor out later on we will reinforce these cracks with hot glue. The First step is to cut out the old capacitor. ![]()
