Seems I have put this in the wrong place again onehundred80 !!

Anyway not to worry seems that the garage that replaced the lamp just before I purchased it joined the two cables together (why I don't know) and did a terrible solder repair right in the middle of the rubber housing between the tailgate and car which had come apart.

Off to shops to get some new wire and hopefully can pull it through and re solder where it does NOT flex. Idiots, and they were a so called prestige repair shop down in Victoria.
