warning light earth

Hi does anyone know where the earth (Black and red wire as per attached) for the indicator warning lights in a series 3 was connected originally

Pretty sure they connect to the gauge securing screws.

Yeah, I'd go along with that. I recall several other lamps (instrument illumination, main beam, charge lamp, etc) also earth to the same place, and I also ran a good earth from there to the bulkhead to make sure it really was a good earth.

By the way, am I the only person slightly worried about having an unfused, unprotected 12V supply on the dash, very close to an earth point (the 'test' terminals)?

I have left the earth connection there connected, but decided not to wire up the +ve supply, but have a fused supply to a (covered) cigarette lighter socket, instead. I hate the idea of unfused circuits on a car.

No, you're not.

I'm putting an inline fuse holder in the +VE wire.

That's perhaps a more sensible option to allow the terminals to still be used. But I don't have anything to plug in there, anyway. A cigarette socket is a lot more useful...and even more useful when a USB adapter is plugged into it.

Thanks for input. I agree with you megaman and will be changing the wiring to the inspection lamp socket.. I am tempted to cut the dash and put a hard wired usb socket in there but may "hide it" as my old 109 is pretty standard and unmodified

I'd love to have an Land Rover (Lucas) inspection lamp to go with the socket.
