I think it hooks up like this:

Do the relays have to be grounded as well? I have both headlight plugs grounded but not the relays themselves. The headlights work right now but I keep frying my tail light fuse.

Typically the relay body doesn’t require to be grounded.
@TheEngineer
12V+ connects to one terminal, 12V- connects to the other through a switch.

Typical relay —
When the switch closes, electricity flows through the little coil inside the relay, creating a magnetic field which swings a contactor to two other terminals, joining them together —.
The tiny bit of current required to flip the relay allows the relay to close the circuit of the high power headlights.

That's what I figured. Somewhere along my installation my fuse for the tail lights got fried. The first twist of the headlight switch kills the fuse but I can still use the headlights. Haven't had any luck tracking down where the issue is. I've checked every ground I touched and still no success.
