In this instructable I will be showing you how your hood switch can trigger your underhood lights. I will be installing LED's for my new KillerGlass. This mod is being done on a 2009 Dodge Charger R/T but should work for Challengers, Maggies and 300's, possibly other Mopars as well.
*note* By doing this mod, your car will think the hood is closed regardless of the position of the hood; therefore, this mod will allow your Charger to remote start with the hood open.
Things you will need:
The usual tools (crimpers, x-acto knife, screwdrivers, 13mm socket)
1(one) - 1K resistor
Heat shrink tubing
Lets get started...
Remove the fasteners holding this grille; remove the grille as well.
Remove this bolt using a 13mm.
Pull this unit out as far as possible. Remove the switch as I have done below.
Cut both of these wires (black&purple/lt.blue) about 1.5” from the plug..
Take the black wire coming from the car and crimp a resistor together as shown below.
Now take the purple wire and connect it to the other end of the resistor. Once done, heat shrink the whole assembly to protect the resistor.
Like I said, be sure to shrink tube the whole thing as to protect the resistor. Now connect the plug as shown. The purple wire from the plug will now connect to the negative side of the LED’s; I will be using about three feet of white wire for this.
Look in the end of the plunger and you will see a resistor, using an x-acto knife, cut it out.
Put the whole unit back together leaving your new wire exposed.
I need to run my wire to the fuse box area, follow the pictures below to see how to run it through the body. It helps to have a roll of solder to pull the wire through. Once done you can replace the small grille.
I am connecting my white wire to the negative of my LED’s.
I’ve connected the positive from my LED’s to the fuse box. At this point my LED’s come on.
Test by pressing the switch to make sure the lights turn off. Now you're done!
