What would be the common switch panel switches and functions on a station-wagon ambulance or combination? Especially a lower-budget one like a Briarean? Would each one have been totally different, made to suit? On mine for example, I no longer have whatever switch panel and associated wiring that was under the dash, but I have two photos of Briarean switch panels I’m using as templates for mine, the gold ’61 that was on ebay (now in England) and a black '60 I know of. I assume these panels utilize pull-type switches, which I have been checking out from ebay and NAPA. I’m not sure if those other items are indicator lights. I think my original underhood siren was operated by the horn ring, but I wonder if there’s a master switch to switch that over, maybe one for the tunnel lights on all four corners, and one for the 17D that was rather standard. Maybe an additional one if an optional fender-mounted siren-light. Or if there's a 2-way radio, is there a radio function switch? Can anyone make a guess as to what these probably are? Thanks much. I hope this info is applicable to other low-budget combos as well. Curiously, the toggle switch I have on the driver’s kick panel wasn’t for lights or siren, but decoding the wire colors it tied-together the left and right rear turn signals lamps for some reason. (Maybe to make the rears flash together with the flasher?)
