Help with Cargo lamps between the high mount brake light

I changed my burt out high mount stop lamp today with a new bulb and it now works. But, in the process, my cargo lamps have stopped working!

To make it worse, I can not find out from the owners manual what fuse the cargo lights are connected too and there is not anything else that has stopped working.

Does anyone one know what fuse the cargo lights are connected too? I have checked the bulbs, they are fine. I checked the bulb sockets with an meter and they both don't seem to have any power.

Cargo lights are connected to the interior dome lights. Did you check the socket with a ground?

HHmmm...... no, I didn't and my interior dome lights all work.. Each socket has two wires going to it, isn't one wire hot and one was ground? Both bulbs show good when I tested them with an ohlm meter, could they still be bad due to me handling them with my fingers?

Yes one side is hot and one is ground, you may have power but no ground to the socket since your interior lights are working. However I’d expect the stop bulb is grounded in the same place which makes this odd, but you never know. The bulbs may prematurely fail from handling them with your hands, but they shouldn’t just die all the sudden because you touched them.

Jon; Let's take a step back and look at this. They were working before you changed the high mount brake lamp, now they don't. You say there's no battery (or ground?) at the socket. The interior lights are still working. I don't know what you have to do to change the brake lamps but I would suspect something got pulled loose for the cargo lamps. Perhaps the ground supply runs from the brake lamps to the cargo lamps.

Thank you for the suggestions, I will work on this again on Sunday. Sunday is the first day I am going to get without rain!

I got some time today to go fiddle with the cargo lights again and got them working! I wiggled and pushed-in the wire harness that goes to the cargo lamps and the brake light and the cargo lights lit up... I have no idea how the lights are connected up between the head liner and the roof of the truck, but they stayed lit after I screwed down then cargo/brake light assembly back down.
