re: "Lights to Battery" A really tough challenge, not even done yet. Ran wiring toward middle light to reduce load on wires. From center light, I ran 10 ga wires along rack to the back, drilled a hole in the roof near LR roof rack mount, pulled interior mouldings. Ground wire will mount to inside rear gate hing body side. Now need to run hot lead down lr pillar and along interior lower mouldings. Just got that for today. Will update as I go. . .
