Thanks for the help folks. It's great the harness will work for 6 or 12. Three more questions; A concern I have with leaving the truck on 6V is the very dim brake lights. (1) Do the inverters that convert 6V to 12V work very well? (2) With an inverter would it make sense to replace my existing lights with 12V LEDs? (3) I've read that installing a relay for the headlights will make them brighter. Is that correct? Thanks for the help (I'm a rookie at wiring).
