You connect the relays to the battery and the headlights. When you turn on the headlights, power goes through the relays to the headlights instead of roundy-round from the battery to the headlight switch, dimmer switch and then to the headlights. Much less voltage drop. Here is a thread I made to show the difference from stock to using the relays. I bought them from LMC.
