Looking for brake light switch on 86 coach . I see the terminal for the hot side of switch (#3 yellow /blue wire ) but I need the switched side  for trailer brake controller .
Thanks,  Chris

Apologies for posting in wrong area . Trying to leave on trip , very late . Found the wire (s) for brake light switched side . Yellow /blue , purple white , red converge near terminal board .

Not a problem. I left it showing in the Emergency thread for the next several days trying to get you an answer. Glad you found it!!
