If you have a Mega Live and the drain wire wasn’t exposed to attach to negative fuse box or negative side of battery, it’s buried at the end of the power wires and you will need to follow these instructions to attach it properly. More info can be read on bbc forum posting. Mega Live Drain Wire

A drain wire is not a ground. It is only grounded on one end, usually at the end the power comes from. Grounding it at the other end makes it a ground and useless for noise reduction .. The wires are wrapped with an aluminum foil attached to the drain (ground) wire to transfer noise and induced voltage to ground. Don
