Sorry if this has been asked before but I just bought a 1998 Tr18 and the previous owner ran new power wires from the navigation and anchor lights up to the Roto switch panel but did not hook up. He also disconnected the wires from the back of the navigation roto switch. So I'm kinda lost on how to install the new wires. Do I need to take the 2 grounds from the new wires and mount those to the ground bare on the fuse panel or what? Then what do I do with the 2 power wires? Thanks for any guidance and help on this issue.
