Cab Lights

[NOS454V8]

Hi there all. I have an 83 GMC longbox 1/2 ton with a 90 Suburban front clip conversion on it. 4 inch lift with 33's on it. 350 4speed, NP208 case. A really nice truck. I like the look of the truck but I think it would really set off especially at night with cab lights. I know what I just said haha I want to drill holes in my perfectly good roof to install cab lights haha. Thats my opinion, I know a lot of people dont care for cab lights but I do. I know people have put them on before and my big question is, how in the hell do you run each individual piece of the lights for the harness between the roof panels? Use a piece of wire or coat hanger or what? Someone out must have an idea. Let me know what ya'll think.

thanks,
Justin

What style of lights are you going to be running? 73-87 STYLE O.E.M.? Or maybe a newer O.E.M. style with only 3 housings instead of five? Once you've chosen your lights and cut your holes, you can take a wire hanger and straighten it out. make a tight loop on one end and a larger loop on the other end to use as a handle. You can then slide this into the hole on one side of the cab and hook the wires through the loop on the end to pull them through all the way to the other side. Now for the hard part...... threading the wires down through the drivers side "A" pillar next to the windshield. This is a real major P.I.T.A.!!!!
If you pull your instrument cluster and look at the side wall behind it you will see an opening there where the wires will come out of so you can plug into the 6 gang ground just in front of the opening and into the parking light wiring near the headlight switch. 2 wires are all that's needed for your standard set up. Just connect the power lead to each lamp terminating at the far right.
Or you could do like I did and run 4 wires up there tying the other 2 into the front side markers and the 2 outside clearance lamps so that they flash alternately with the front turn signals. If you go this route, DO NOT HOOK UP THE GROUND LEAD TO THESE TWO LIGHTS!!! You will have 2 power leads going to the outer lights, one for the parking light power and the other for the turn signal power. and it will look like this when and if done right.......

I would be running the OEM 73-87 style ones. Doesn't sound too bad just time consuming but worth it in the end IMO.

I added cab lights to my truck, the hardest part was getting the wire down the A-pillar, I don't have a headliner or any trim. With a little work I got it done and I love mine.
