Run fog lights off headlights?

[CTScott]

You still need to wire them through the fog light relay, as just paralleling the fog lights with the headlight wiring would be too much current draw for the headlight circuit. After you make the connection through the under hood fuse box and insert the fog light relay in the OEM position, you can jump the switch side of the fog light wiring to the switch side of the headlight wiring to make them come on with the headlights, and not have a separate switch.
