i want to connect another wire to it how do i do it?
need more info. Where, a car/ vehicle? an appliance? Wiring in the home? a project? Will come back periodically to check Wingman
depends on the wire and what is on it. It may be as easy as soldering a wire to it, or buying a parallel connector adaptor of some sort. A 11kV power line, that requires special tools and lots of precautions. And permissions. .
