Hello All,

First post and i need help

I'm the proud new owner of a 2015 Discovery 4 on the second night of owning it I had an LED strip light stolen from the front of the roof rack.

I just had it replaced on the insurance and it's now spot welded in place so shouldn't be as easy to steal but I'm thinking about fitting a motion/proximity sensor so the the alarm triggers if anyone gets too close. (I also have a winch which was pretty expensive.)

The sensor I have seen says "The 508D comes supplied with a 4-pin harness which connects between the dual zone motion sensor and your vehicles alarm module."

I know this is a very basic question but where would I look for the place to attach the harness on my car?

I tried using the search function on the forum but didn't get an answer...
