Cab marker lights install, part 1

[Instructor31]

Nice. Only advice I can give you (not that you’re asking for any) is to make sure it’s sealed up well with a flexible gasket. I did this a year back and have gone through 2 sets of lights due to condensation. Might just be the type of lights I got but it’ll eventually get some condensation in there.

I bought OEM lights from one of the discount GM parts stores online.  I paid more than what aftermarket lights cost but I figure that’s what came from the factory so they should be good.   I put a bead of clear silicom between the lights and roof when I installed them.  Never had any issues with water leaks or burnt out LEDs.

That’s good to hear. I can’t figure what’s the cause of mines. Might be the gasket type I’m using honestly and a combination of dry/hot weather where I’m at.

What brand lights did you buy?

They shouldn’t have any condensation if they’re sealed.  You should put a bead of silicon like I did. 

[Instructor31]

I have, Ive bought two styles. One with a single led and one with multiple led’s in the housing. 

 

The one with the single led didn't come with any sort of manufacture sealing around the led. The one with multiple led’s did. Both still got condensation. 

 

Ill probably redo the wiring again and change silicon brand.

I had bought the punch off of CuzznVinny. It worked great and no mess from the dremel. The holes still had to be cleaned up a little, but it was quick and easy. I was still very nervous punching that first hole.

Do you Still have the punch?  Im tackling cab lights soon and looking to buy the square punch.

If if you look closely with a magnifying glass you can see the numbers printed on the plastic connector next to the pins.

Yup, still have it. I paid $50 for it. Would sell it for $25 plus shipping. I only used it once. Send me a PM if you are interested.

Thanks
man!!

Test them first I had the pins but no power to them. Had to tap into the harness going to the mirror in the passengers side kick panel.

Pin 3 appears to have power - where did you run your ground?

 

Thanks for the help!

Ok NEW question... tested pin 3. It’s hot even when truck is off and no key in ignition.... I’m looking for the pin that’s hot all the time or just when running lights are on?

[Jaychevy81]

I am pretty sure that passengers side plug is for the plow prep package. It feeds the cad lights and like a roof beacon. You want the pin that works with your parking lights.
