Foglight Prewiring?

if you are going to bypass the factory wires, just wire straight from the switch to a standard $5 bosch relay.

on my toyota truck, even when the factory used a relay for the headlights, i saw a .6 volt increase when i created a new wiring circuit.

the factory wiring is usually thin, like 20-18 gauge. i went and used 12 gauge and saw the increase.

so, if you are going to do that, just remember to use thick wires.
