I decided to have another look at things to confirm wiring. I pulled the headlights again and confirmed the following:
1) The headlight wiring harness on the Sport trims only have 3 wires (out of a possible 6). There are plugs/blanks in the empty spaces. I played around with the connector a bit but I don't know enough about it to figure out how to add a 4rth wire on my own. I also tried to see how a replacement harness might connect to the jeep - such as the one listed on the Mopar LED headlight package. I can't see how a replacement harness would work. Here is a pick of the connector:
2) I confirmed that the halogen headlights expect a 3 wire harness (although it wouldn't be a problem if you supplied 4 (like a Sahara or Rubicon probably does)) and the LED headlights expect a 4 wire harness. Here are picks of the wiring port for each headlight. Halogen first then LED:
While I was at it I decided to clean up under the hood a bit...
So thats it for today. At this point I am waiting to see what the wiring harness looks like in the LED headlight package. At the same time I am going to talk to some folks about adding a 4rth wire to the existing connector. I figure I could patch into the parking lights and turn on both the LED switchback parking lights and the halos at the same time using the parking lights as my DRL.
