Okay I have a 2005 Jag which assembly rusted I went out and bought an assembly from a 2007 to find out that it was an H ID assembly upon installing it I found out that the highbeams work but the low beams do not how can I fix this problem electronically avoiding the purchase of the original 2005 headlamp assembly?

 

Welcome to the forum Jag2005

I moved your post from the X350 XJ section to the X-Type section, as your profile says you have an X-Type.

So if I understand correctly, your 2005 model does not have HID / Xenon headlamps, but the replacement lamp you bought from the 2007 model is HID / Xenon?

When you get a moment stop by our new members area and introduce yourself.

 

Jag2005, if you look at the plug that you plug into the headlight assembly, you should see a black wire in the #9 pin spot. To make the HIDs work, you need to add a new black (ground) wire to pin #10. There is a slight wiring difference between the non-HID and HID headlights. Once you do that for both headlights, you will have HIDs that will function just like your old headlights did.

 

Thank you much Thurmo where could i pick up this the wire? and would you have instructions on how to install it? Sorry if I'm asking for much but my car has been in the garage for almost a month.

 

Jag2005, unfortunately, you would either be looking at pulling a wiring harness out of a wrecked car to get the complete wiring harness or you would need to get your hands on a damaged wiring harness, pulling a pin out of a connector and then sliding this wire into your existing connector (in slot #10) and then running this wire to the chassis ground point that is under the headlight assembly. If I need to go into more detail, let me know.

 

Please I'm not savvy in this area but ill try my best with a little more details and if possible some pics I'm also a visual person. Not to be redundant but i couldn't get this ground wire at an auto part store?

 

Jag2005, if you remove any plug on the car, you will see that one side has silver spikes (called pins) that slide into silver lined holes (called receivers). Your headlight assembly has the pins in it (permanently mounted) and the plug has the receivers. If you look closely at the plug, you will see very small numbers imprinted on the plastic where the plug attaches to the headlight assembly. If you look in the number 10 slot, you will find that it is empty. So, what you have to do is to find one of the receivers to go into the plug opening that has a wire attached to it (can be soldered on or a lot of them are a crimp style connector). You can then remove the side of the plug where the wires go in and slide this receiver into the #10 spot and then reassemble the plug. The other end of the wire I would recommend putting a ring lug (looks like a washer that has a crimp connection attached to it) on the wire and then removing a bolt that is under the headlight assembly and putting the ring lug there so the bolt holds the ring lug down.

As for finding the receivers. This is the challenge. Sometimes if you go to a big auto parts store, you can find them on the rack there in the store. WARNING!!!!!!! There are many pins that look alike. You need to make sure you get the correct one. The big difference is some have little metal "slivers" sticking out at various points. These "slivers" are actually retaining tabs that once you slide the receiver into the plug, it locks the receiver in place. Every manufacturer has their own little twist on this. if you can find some for "Ford", you stand a better chance of these working for you. Finding some that specifically call out Jaguar is going to be a real needle in a haystack find. This is where getting an old plug and removing it from a car can be the easier route as you will already have the receiver with a wire attached that all you have to do is remove the receiver (a jeweler's screwdriver can normally be used to push the "sliver" back in and allow the receiver to be removed) and then you can bend the sliver back out and slide the piece into the headlight plug.

 

Can't thank you enough for the info. Thermo thank you for taking out time to help me. The amount of money saved is priceless. Thank you sir.
