The factory wiring in modern cars is light gauge and is not designed for additional loads. Then run a heavy gauge wire from the battery to the relay placing a 30 amp fuse in line very close to the battery.

Automotive relay diagram relays are switches controlled by electrical power like another switch computer or control module. Relay terminology the iso mini relay we have looked at above has 4 pins or terminals on the body and is referred to as a make break relay because there is one high current circuit and a contact that is either open or closed depending upon whether the relay is at rest or energised. The purpose of a relay is to automate this power to switch electrical circuits on and off at particular times. Follow the relay s wiring schematic when connecting the wires to the relay one of the relays terminals goes to ground.

Wiring with a relay allows the power to run straight from the battery through the relay mounted nearby directly to the lights. Do not connect the power to the battery until all wiring is done. See below for an example of a relay wiring diagram. A relay can be used to power a new circuit with very little added current draw on the original wiring.

The following simplified circuit diagram is often used to easily understand how a relay operates. Buy relays pigtails and kits here. The interior mounted switch only draws minimal power though the interior fuse block to activate the relay.
