I recently purchased a 2014 Leprechaun 319ds, while changing out the front head unit, I noticed this bunch of wires. All unconnected, heavy gauge (for behind dash) There is a small plug attached to one wire with the label "trigger" They do not appear to be Ford factory. and they do not appear to be rear camera related.
Does anyone know what they were for?
Battery boost? Trailer controller?
While I'm on the subject, has anyone successfully installed upfitter switches on their e-450, factory trailer controller?
