Tail Lights Inop

[68FLFORD]

Parking lights, brake lights, reverse lights and blinkers.....all blacked out. Everything worked until I removed my rear bumper/trailer light adapter and then discovered the dreadful blackout the following day. I'm guessing something was grounded and now is not?? I am by no means familiar with any aspect of this situation. I am going to check the fuses when I get back to the house. Could it be something else? Trying to narrow possible problems. Any help would be appreciated. Thanks!

the tail light housing grounds to the bed via the tail light housing screws. the side marker light on the 70-72 ground via a ground wire behind the tail light housing to the bed. more than likely there is something that was unhooked that shouldn't have been unhooked.

I'm guessing something to do with the Trailer Light adapter...
