Hey, I decided to give back to the community after taking so much! Hope this helps you guys! Thanks to JTJohnny102 for help with the wiring!
Materials: Sidemarkers with wires, bulbs, Wire cutters/strippers, electrical tape, solder and soldering iron, two different color wires (one color will do), Dremel tool and cutting discs(1 will do), safety googles and sanding mask.
1) Measure and mark the area you want to cut with a white crayon or tape. The crayon will rub off.
2) Use a dremel tool to cut the marked area out. My dremel was 35,000 rpm which was really fast so i kinda messed up. Touch up paint will fix it.
3) Insert the marker to make sure it fits correctly and make any adjustments.
4) After adjustments, go on to pull off your corner light housings so you can do the wiring. There will be a screw where the corner headlight is that will release the corner light housing. Then pull the sucker off... its a pain. There are two bulbs that you will see when you pull the housing out. One blinks and the other does not. Make sure you wire the sidemarkers to the blinking one. To check which is which just turn on your blinkers!
Okay, so now get your extra wire that you bought (one of the two colors) and splice it into the positive wire of the blinking corner light. You do this by stripping the wire around it and twisting the new wire around and and soldering it together. Then wrap it in electrical tape. You can also buy wire taps which are a lot easier and save you time. The positive wire is the blue one on the right side and the yellow one on the left side.
5) Measure the length of wire you will need to run it do the sidemarkers then cut it with the wire cutter. Run the positive wire all the way through the inside of the fender and under the wheel liner. Then tuck it into the wheel liner and run it down toward the sidemarker hole. This is the tricky part, because i had to use a clothes hanger to grab the wire to pull it through the sidemarker hole.
6) Okay now its type for the ground wire. You have some choices. You can wire it to your chassis ground or splice the ground on the corner lights, which is the black wire next to the positive wire. I chose the chassis. So, I measured the length of wire I might need and wired it to one of the ground points in my car by wrapping it around the ground cables.
7) Then, I ran the ground wire all the way back to the corner housing and back to the sidemarker hole like in step 5.
8) Okay now that your positive and negative wires are attached to the car, we will begin wiring it to the sidemarkers. Strip the positive and ground wires about 1/2 inch. Then strip the wires that came with your side markers the same length. Twist the wires together, positive to positive, negative to negative. Then solder them and wrap it in electrical tape. Tape up or tie any excess wire lengths.
9) Insert the bulb holders and bulb. I chose xenon white bulbs.
10) Then use touch up paint to line the sidemarker holes so that they don't rust and touch up any mistakes.
11) Attach the sidemarker to the bulb holder and insert it into the hole. Test the lights to see if they work. Then use some silicon adhesive to attach the sidemarker to the car and for added water protection.
12) Reattach corner lights and your done! Congrats now you got sidemarkers!
