I have done some extensive google-fu and read thru several threads, but am coming up short so forgive me...

Recently purchased a used leer cap, it came with 2 wires tied into a 4 prong female? end coming from the third brake light.



I am looking for the other end of this plug if at all possible. Or a way to integrate a plug separation like this from cap to my bed.
There is no dome, so it is just two wires that I will be splicing to my brake light.

Your help is appreciated. Apologies for any ignorance here.

 

Is this wiring harness what you are looking for?
