well your right, but I think each door wire goes to either a central point, which feeds onto the interior lights, or and I'm kinda hoping it does they are all fed to a relay that then triggers the interior lights. The only problem I can see with wiring it up to the light itself which is perfectly do'able and safe is the GPS will not trigger if the bulb has failed. The relay would switch even if the bulb has gone and thus trigger the gps, and I was kinda hoping that somebody on here would have jumped in by now and said weather or not there was a relay. Sorry due to work load I havint had time to look at the gps, never mind fit it or my new radio and next week I have my new series style doors arriving and her indoors has a pile of odd jobs waiting for me too.....its nae wonder I drink
That's good info, John. I'll investigate the door switch/light relay. Kwakerman sent me a set of wiring diagrams for the 300Tdi, so I'll have a look through them. I'll let you know what I find out. It's a nightmare when the Mrs has plans! I think I'm a relatively free man this weekend Still be on the drink tonight though
