How-to: Install LED Glow Underbody Kit

First off, I did not take any set up or during shots. I just wanted to give ideas to others looking to install how they could go about it. This is also my first attempt at a How-To for anything and I also had no clue what I was doing going in, so...follow at your own risk!

The screws this kit come with SUCK! so do yourself a favor and go buy some good socket in screws. $4 at ACE hardware bought me 100 which is like 70 more than I could have even thought of using here.

------------------------------------------------------------

Here are the tools I needed beyond what the kit included:
A power drill
a socket driver
and an adapter to use my drill to drive the screws in real tight.
and a drill bit (no picture) about half the diameter of the screw to drill pilot holes. Ask the guy/gal who helps you find the screws to recommend you a good bit to pair with it if you do not know what you're looking for.



Tools/parts I opted to get that you can change out as you desire:
Electrical tape (color matched )
A 1.25 inch cord grommet (color matched or painted)

--------------------------------------------------------

My mounting process:
Some of this is pretty common sense, so if you know what you're doing you can skip over this for sure.

I clipped on the mounting clips. I than taped the tube where I wanted it to be with some electrical tape.
Drilled one pilot hole
hand tighten a screw in
next pilot hole
repeat until the fixture is drilled in
Now take the power drill and tighten the screws all the way through the whole fixture.

Once the fixture is mounted, navigate the wiring toward the back.

---------------------------------------------------------

I drilled a 1.25' hole in the bottom of my trunk to rout the wires through. I have yet to seal, as I am not 100% on my cleanup just yet, but you will need to seal it to lock out moisture!!!

I used the grommet to cover it up some and make it look a little neater. Remember you will need a slightly bigger hole than just the wire width as you have to fit those plugs through too.

-----------------------------------------------------------

The absolute hardest one to wire, or at least for me to figure out how to do, was of course the front bumper. This is what intimidated me from doing it a while ago.

I cannot get a good picture of it, but mount the wire on the passenger side of the tube. There is a little plastic piece you can run it over and through a small hole between the fender and the plastic piece that lines the passenger tire well.

I then removed enough rivet things and bolts to tuck the wire along the wheel well till it was on the other side of these plastic rivets, well the image only has one, but there are two on the top side of the wheel well:

I did that just to make sure it stayed in and would not get caught in the wheel.



Here's a really blurry picture comparing the screw the kit came with to the one I used.


One of the grommet in the trunk


Passenger side. You can see the wire tucked in coming back from the front light.



Mounting of the front:




Mounting of the rear:


For the Driver side, I ran the wire under the exhaust shield and to the axle frame(?):

Exhaust shield, I tucked the wire behind the other wires:



Than I ran them all together to the trunk using 2 of the provided zip tie hooks:



Make sure you find a way to keep the wires tight, mine came a little loose after a short drive so...yea, make sure they are secure before moving on.

Good luck and have fun.

Thanks for any feedback. I know this could have been done better, and I do not have a way to get the car more than a few inches up with ramps so my pictures are not the best. So I hope I at least help someone else decide its not worth paying someone else to do it.

Note: At normal height/tilt the LEDs are not visible. The picture was take at a lowish angle toward a car that was tilted away on a slight hill. Also, I know the side ones are mounted a little to far forward, but in order to get them both lined the same and on the back side of the pinch weld, I didn't have much choice.
