Tail Lights out Again

[93SHO_2]

Is there a fusable link in the wiring harness going back to the tailights? This my second 93 SHO I have wired for a trailer hitch. The first one worked fine for 5 years then the tailights quit. The bulbs are good. My latest SHO I had for 6 months just blew out the taillights again??

Have you checked the BOO (Brake On/Off) Switch?

All 3 brake lights work.
The reverse lights also work.
Tail lights are out but the front marker lights are on.

I Replaced The Barke Light Switch On The Brake Pedal, No Help.

Is There A "lamp Out" Relay Or Module Somewhere?
