Many of you want the "Audi" (and now others) look with the LED strip on as DLR. So far the only option is to pay about $ 2,800 to exchange w. Arden aftermarket headlights.
There is no coding (software) option. Technically impossible because LED strip is hardwired parallel to tail lights. So if LED is on, tail lights would come on if you power them up.
Solution:
On headlight main plug, pin 2 (left and right) is powering those LED strips. Cut the wire close to the plug. Run ignition/acc power from fuse box in passenger side engine bay close to firewall. Place inline relay close to headlight plug. Power acc. power on, relay disconnects power from headlight LED input and powers from ignition on all time. When ignition is off, relay drops and reconnects to original wiring scheme. (Later is necessary so your parking lights keep working).
I took a few pictures and have diagrams and pinouts. It works great. LED strip is not the brightest but just right for my taste. Having a black car I like to have some DLR on front but don't like the main or high beam always on as is the only dealer option available. If you are interested on pinouts, pictures and diagrams send me a message.

 

thank you so much for this write up.

maybe this weekend ill grow a pair and attempt this

 

Hi. Interesting. How difficult is the work (can a layman do it himself).

Would appreciate if you could send the diagrams and pics.

Thanks in advance

 

Very nice , Love the spoiler. wonder if that would fit 08 XKR vert ,anyone know ???. BL
please deleat

 

Sorry for the above post mistake. Please send pics and info , thanks BL.

 

Does anyone have the pinouts, pictures and diagrams for this. Can you send it to Mets1525@gmail.com. Thanks in advance

 

Hello,
I'm also interested on this topic.
please send me pictures and diagrams to :

armindo_a@yahoo.com

thanks in advance

 

Here is the complete instructions that Gears put up in the past.

 

Can you please post pictures of the LED on. This is a great DIY. Thanks Floyd

 

Signature light hack complete!

in case anyone is a little confused with how Gears drew his wiring schematic (I admit, I was...and even wired it wrong the first time because I didn't know which part of the Tyco relay was normally open or closed.) So, I drew this up



Oh, it also helps during this project to get some special connectors that fit onto the PCB pins of the Tyco relay. Ebay to the rescue!

Here is the complete instructions that Gears put up in the past and added new clearer diagram by H20boy. Thanks

 

I was wondering if anyone has done this hack on a MY 2014 or 2015 XJ because he cable colors look like they have changed for the PIN#2 on the passenger side harness so I want to be sure do I follow the PIN# or try to match the color of the cables shown in the instructions. Thanks a bunch!

 

Alex, I'd say stick with the Pin placement instead of color matching the wiring. To test it, since it's an LED, you could use a 9v battery to test Pin #2 and see if it lights the bar and marker light. Don't forget to ground the harness to the battery (-) side

 

Will do. I will try tomorrow and update the thread for future MY2015 people who want to do this. Thanks again!!

 

Many thanks H2Oboy. That was correct info the pin 2 is still the same PIN for the LED lights for MY 2015 as well. In my case I used 2 seperate relays so I would not need that much wiring all over the front. All works pefectly.....

 

So what color is the wire so we can update the directions, please.

 

The drivers side is the same color as in the pictures. The passenger side is a purple cable in PIN#2.

 

I have updated the "manual". Thanks to all the contributors.

 

I would like to see pics of the wire break-in to get the LEDs on 2015 xj to turn on with ignition.

Thanks
