Here's a few pics of my install. I found a color code from autocommand.com for alarm wiring which gave me the code for the parking lights. I decided to use that as my trigger for my relay, as opposed to using the fog lamp stock switch. (This way I can use these with High Beams on)
I installed my lights and ran the wiring under the cowl. The cowl is removed with 7 screws. 4 can be seen below the windsheild. 1 is in the center of the air vent. The other 2 are UNDER the weather strip when you open the hood just slip it up on both ends and there they are. (Noted in pics)
I then ran the wire from my light Under the hinges .... the wire Just slid through without any ends on it. I don't think it will be a problem if I fold the windsheild, but I doubt I can do that anyway with these lights on there. I then used heat shrink tubing to seal the connection so water doesn't get in there. For the Passenger side I ran the wire through a gap under the cowl out of the way so the wiper arm doesn't catch the wiring.
NOTE: First install I tried grounding my lights to the mounting bolts of my lights..... it worked for 15 minutes. I now need to take the cowl off again and run some ground wires .... learn from my mistake, do it right the first time, there are plenty of screws and bolts under the cowl to run a ground to.
To run the wires inside I simply ran then through the same hole the wiper wires go through. I then ran both wires to the output of my relay for my lights. The relay is activated by a switch that is powered by my parking light wires, so I can turn the lights on and off anytime I have my parking lights on, but they won't stay on when the lights are off. The Relay itself is connected to dirct 12v from the battery .. I still need to add a fuse... Below are a few pics of the install. I have some more detailed pics if anyone wants them just PM me. I will also get a pic of my inside switch install when I get some daylight ... damn I wish I had a garage.
ALL ABOVE MODIFICATIONS WERE DONE ON A 2003 TJ
P.S. I dropped a screw in my vent whil reinstalling my dash .... any help on getting inside my vent like via the blower motor ???
