Dean, I am trying to put a trailer brake controller on my '93 Magna. There is supposed to be wiring in the front of the coach to use for that purpose. Greg at the factory told me it would be under the dash, in the front run box or in the shifter console by the drivers seat. Well, no luck on any of those places and I can't find the brake pressure switch either. I did find a reference, in my wiring manual, to a spare wire #4 that was a 12 gauge red wire running from the front run box to the rear run box. Can't find that either. So before I post to the CC forum, have you got any ideas where i might look for these wires and the switch? Thanks in advance. Joe
