Mounting Brackets for Square Eights

If you have single bullet connectors for the earth's, part them, remove them and fit double bullet sleeves in their place, then you will have spare capacity to plug in earths from your lights - simple !

To test blue / yellow continuity from front to glovebox just connect piece of wire to one of the blue / yellow's at the front and take it to the glovebox and use your meter there - simple !
Good ideas. Many thanks. Sometimes I miss the obvious!
