How To: Aftermarket cab marker lights.

What you'll need.

Wire
Wire cutter
Electrical tape
Phillips and flathead screwdrivers
drill
5/32 drill bit
Sharpie or paint marker
Measuring tape
patience

Ok so u got a set of cab markers and want them to look factory. Well what u need to do is find dead center on the cab of your truck and mark it a few inches behind the windshield. Next measure the width of your marker lights and divide in half. For the center three you want to center the middle one and measure the distance u want between them and add the full width of one light (if your lights are 2 inches add that to your measurement to find center). Do the same on each side. Next you need to mark for backspacing from the windshield. Measure from the rubber back to where u want the front of your light to be And mark it. I chose 2 inches. Now u have your center three marked. Next measure in from the sides of your truck to where you want your outer lights. Add 1/2 width of your light to your measurement and mark. Then do your backspacing.
Next open one of your lights up and place it centered on your marks where it's going to be And mark where the mounting holes will be. Also mark where the wire will go through. Double check your work before drilling and drill your holes for all the lights.
Feed the wires through, mount and button up all your lights.
Next move inside. Take your wire and start on the passenger side. Connect each light to the wire using quick connects so you have a string of wire like a Xmas light set. Work your way over and run the wire down to under the dash.
Next we connect to the headlight switch. On my 85 it is the brown wire on the switch.

Now admire your work. That's all she wrote. Thanks for reading.

I love the cargo lights. I would put a set on mine, JC whitney has them and they are not to expensive, but I refuse to drill holes in the cab of my truck. Didnt some of theses trucks, earlier model I think, have a factory cargo lamp switch that was on the rear post on the drivers side, next to the coat hook?

yea same as mike mine werent but $20.
Now this is where the 88+ wiring is different. After you drill your holes and run and hide all your power wires to your lights you will want to take off your dash. on your rocker panel for the marker lights and headlights is a connector in the back. you will want to take off that connector and open up the plastic clip holding them on. strip your power wire for your cab lights about a half a inch up and the connect them into the same terminal as the black wire. I.E. the one furthest to the drivers side on the harness. you can see the black and red wire together on the right of the picture. (this was taken under dash so its from the bottom.) the red wire is from the hot on the cab lights and the black wire is the factory marker light power.
