If they were tied into the factory connector that would be om the driver side of the cab, behind the kick panel and above the hood release handle, it's a flat 2-wire grey connector, IIRC the wires are colored brown for power and black for ground. Said connector is then wired into the main dash harness, the brown wire eventually splices into the wire for the front and rear running lamps that comes out of the headlight switch. Don't recall where the ground goes, but pretty sure it's also spliced into some other circuit for a shared ground. So if you're checking things check the connector's brown wire for power when the front and rear amber lamps are lit, and ground is ground always.
