Went to fix what a homeowner started. He wanted lights to work temporary so he rigged it up with an extension cord. Traveler was tied in with neutral on cord common and other traveler on traveler screws and hot from cord on common screw. He also had started running wire and for his 3 ways he ran 3 wire from switches to light not switch to switch and he ran some in 12 some in 14. It was fun.
