I have just installed an led strip light above the rear door of my 1996 tdi
90 Defender CSW. Positive power is from a cable leading direct from the battery (with an in-line fuse) and the earth is connected to the "plunger switch" by the rear doorThe light comes on as expected when the rear door is open. Unexpectedly it also comes on when the passenger door is opened (but not when the driver door is opened)
I cannot work out how it comes on with the passenger door as the earth wire is not connected to it (the light unit is "sticky taped" to the roof lining). If possible I would like the light to come on with the driver door as well
Advice please
Julian
