Does anyone know where I can find a replacement for this wiring harness for the third brake light? 1995 F150

 

I'm not aware of any aftermarket options, used is your best bet. Either Ebay or a Junkyard.

 

Found the sockets with pigtails on Bronco Graveyard and am going to splice them into the harness. Didn't have any luck finding an aftermarket harness so that seemed like the next best thing. The sockets were like $4 each plus shipping
