I was able to solve the brake leak by changing out the stock steel Wilwood M/C adaptor for a brass one. Nice soft brass seals better.
I've got 4 tail lights, so according to the guy at E-Z wiring I will not need any relays.
"Turn Flasher" is the power from the flasher into the turn switch.
"Hazard" is the power from the flasher into the hazard switch, which then gets spliced into the parking lights at the load side of the switch.
"Brake Switch" picks up power for the brake lights once I find a hot wire to hook it to.
Thanks for the help!
