Thanks to everyone who takes the time to reply and educate!

I just picked up a 2010 Commander that spent a few years in England, and the PO had it converted to Euro standard lighting - front fender markers, and amber tail turn indicators. Cool, but the down side is that I no longer have backup lights! That part of the assembly has an amber 3057A bulb and flashes when turning, while the lower red portions do NOT flash.

I have checked the tail light wiring harness section, and it has not been altered. So far, I have not looked deeper into the wiring, not until I ask you guys a few questions...

1. Is there a free 2010 wiring diagram available? I've searched, but nothing came up.

2. Is tail light function dealer programable, or did someone do some major splicing?

3. Is there a backup light fuse or is it lumped in with something else and I missed it?

This is a US Domestic vehicle, not a Euro export build so I should think there's a way to undo what has been done. Thanks for helping out! I'll add photos soon...

@Portholes; Welcome to the forum; I'll give you the information that I have and some other information that may help you, it will be up to you to sort through it;

As far as I know, the wiring diagrams are pretty universal through most of the Commander model years, but, since you have the model with the funky European tail lights, I don't know how useful it will be; I'll give you what I have - if it helps you great, if not, well - I tried.

I'll also give you a link to a thread that gives a lot of information about fuses and the Commander's Junction Block; The wiring diagrams will be at the bottom of this thread as attached .pdf's here is a link to the fuse/junction block information;

Hope this helps.

So here are the photos...

Thanks to Big Blue for the links; I'll be combing thru the details tomorrow. BTW, there is no power to the 7-pin trailer connector backup light position either, so now I'm almost hoping the dealer can come to the rescue.

Does anyone out there have the AppCar Diagnostic tool and can see if Euro lights or Backup on/off is an option?

No problem; I have the AppCar DiagFCA OBD-II software, but, you have to have it connected to your XK to see what options are available & unfortunately, I won't be home for another month.

It almost sounds to me like you have a blown fuse somewhere - or a shorted wire, or both.

I've been working hard tracking down the spot where the PO had the turn indicators cut in to the backup light wiring. In the meantime, I bought the AppCar program and a suitable USB/OBD cable. Good stuff! The European options programming does not allow you to change that wiring through the computer, but it's fun to work with some of the other options available.

That program will open up a lot of new doors for you (as I'm sure you've noticed) that you wouldn't have had access to otherwise.

@Portholes; There is a fuse for the 7 pin connector in the Junction block, find it and make sure it's not blown;
