No brake lights after steel tail light conversion

[TheHighHeat]

I replaced the stock boxes with the Desert fab, steel taillight boxes(they use incandescent nulbs)

I had the drivers side working because they accidentally sent me 2 drivers side boxes so I had the drivers side installed for a while before I tried to do the passenger side and it was fully functional, but then I tried to install the passenger side and wasn't paying attention and shorted the reverse lights. I blew out fuse #10, replaced it and the reverse lights worked again.

I just went and checked the wiring again and it all seems to be correct, I tried both the driver and passenger side turn signals they worked fine, pressed the brake pedal, no brake lights(3rd light worked), turned on the parking lights, turned on the turn signals with the lights on they worked fine, turned the lights off and tried the hazards and only the front signals worked

I also have an electronic flasher installed, mine went out about 6 months ago and I just replaced it with an electronic flasher.

Any ideas as to what is going on? Thanks, Jamie

I went and bought a circuit tester, tested all the fuses one last time just to be sure, they all checked out, so then I started from my taillight and tested the circuits, it appears that some how both of my converter boxes are bad even though they are almost brand new, I guess I need to get higher quality ones, anyone have any suggestions? I was using the hopkins brand from advance auto...

Always disconnect the battery when you are working on electrical stuff.
