Thanks for your assistance so far. Thanks JW1982 for the part number required... I'm going to submit a parts request to Ford shortly.
I purchased the light units brand new from a supplier on ebay: ultimate-lighting (http://www.ebay.co.u...984.m1423.l2754). The units don'y have the bulb holders with the lights hence the post but they do each have a little blue connector that I assume links with the part number you have mentioned above?
