How To Install A Dome Light

The Scott Drake dome lamp assembly has two wires-red for power and black for ground. You can ground the lamp at one of the mounting screws or to a separate screw; this is how we grounded ours. All you need is bare steel at the screw for a solid ground. It's a good idea to use a star-lock washer to penetrate the factory primer.

Jim has pulled the windlace and detached the headliner. It's easy to feed the power lead across and down the sail pillar. This gets the lead into the quarter-window area. If you're lucky, your hardtop will have a fastback wiring harness, which some did, and dome light power will be available without having to look underneath the dashboard.

Using the provided screws, the reflector base is installed into the factory dome light screw holes. If you're installing a used factory dome light reflector, Ford has provided a single screw hole not visible here. It's slightly to the left of body center, close to the lens screw holes.

Jim installs the lens using screw holes in the reflector.

The dome light power lead is carefully fed into the sail pillar, which isn't as easy as it looks. You must get the lead down into the quarter-window area, yet clear of the window's up-and-down movement. Follow the taillight harness and zip-tie the power lead to it. Then feed the power lead into the rocker panel.

The power lead should come out here, at the rocker panel. To reach your Mustang's factory wiring harness, you'll need red 14-gauge wire, a female bullet plug, and a male bullet plug. Zip-tie the lead to the taillight harness.

You can get power without removing the instrument panel, but we suggest routing your power lead behind the kick panel and instrument panel, following the main wiring loom. Zip-tie the lead to the main harness and down to the courtesy light plug found below the wiper motor.

There are two power plugs beneath the wiper motor. You want the black wire with a blue stripe, which is the console courtesy lamp plug. If you have a console, use the pinch splice plug provided in the kit.
