Scratch what I said about single pole switches ... we need double pole switches to make things work right. So, DPDT or DP3T would be the necessary designations.
And, I see what they did with switching both sides of the circuit ... the turkeys!! (And stronger expletives.) Unconventional but easy in terms of manufacture. (Conventional wiring would have been just as easy.) However, it creates a potential for being a royal PITA when it comes to trouble shooting. (We'll go with conventional switch wiring, to avoid causing confusion for someone down the road.)
On another note, I really hate -- really, really hate -- really, really, really hate -- working inside a dash. Working on the backside of instrument clusters and similar dash 'faceplates' is okay but actually working inside the dash isn't. (Did I mention I really hate working inside a dash?) I'd gladly trade rebuilding an automatic transmission to have someone else do the contortions required to actually work inside a dash.
