this is probably a simple answer, hopefully. what is the easiest way to mount the 'motor ground' wire on the solenoid motor for the Warn M8000? its on a YJ, the wire is super short. my question is where is this wire typically and most easily ground to? does it need to be to a non-painted surface? is the grille, or the winch mount, or the frame the best? is an extension sometimes needed? thanks for the help.
