Switch/Wiring Suggestion

Below is a pic of a wiring diagram for my light set-up. I want the option to have the lights on with high beams, off altogether or on independently. Would I replace the current rocker switch with a 3 wire on off on switch and install an add a circuit tap in the fuse box at the high beam slot? Would I cut the red hot wire at the new switch and add the add a circuit tap?

 

Post a pic of the connector to the relay showing the wire (colors)

 

You lost me why?

 

Because that diagram makes no sense. We need to know how they are plugged into the relay and why it appears you only have one power/ground source for two circuits..

 

'cause I can't find my chicken bones hidden inside the swamp rat sack...

But I did getya this here:
