Tap the red wire of the Lexus GS F-Sport Fog Lights to the thick green wire you just located. Wrap up the electrical tape in the wiring harness and use a zip-tie to secure. Tap the red/black wire to the ground.

NOTE: We recommend hard wiring the connection, as opposed to using T-Taps. T-taps may have a chance of resulting in a loose connection, whereas hardwiring is more secure.
