When the drivers door is open it exposes a couple of wires. Don't suppose anyone knows what they're for? I have no idea if they standard or for something aftermarket.. Hopefully the pictures will show you everything you need...not sure why wires would come this way to the door when all the other wires use the channel below..

Thanks,

Little plunger thing that turns on the interior lights when you open the door.
Forgot what year you have. Should put it in your profile or mention it when you start a thread.
These are for a '97 to '01 according to the listing.

Thinking you might just be missing the plunger part itself.
Not the whole harness that Ebay shows.

 

Nailed it! On the hunt for one in the UK now, thanks for your help. Mine's a 97, will check my details now to make sure they're correct.
Thanks,
