That is correct, all done on visor. Basically all you are doing is pulling power from vanity light (red wire) and supplying power homelink unit over yellow wire. Reason for cutting/capping so not to feed power back.sweet! To be clear and make sure I understand correctly. all the splicing is done on the new visor itself that was purchased. Nothing was done to the cabling attached directly to the vehicle on the driver side of roll cage?
