heater under 2nd seat - 4x4Poet -

[Burbinite]

I'm curious about the location of the pull lever. My 4x4 has a hole in the dash that is now covered with a cheap plastic plug that I assumed the PO had drilled for some reason. It is located slightly above the ignition. Is this the correct location for the lever? I also have some device that almost looks like a shutoff valve attached with factory style clamps on each heater hose. Could that be part of the rear heater system too?

This truck has nearly every option including the spotlight...maybe there were more and they were removed...

I have also heard about an electric heater mounted in the rear... My 2wd used to have one of those.. so says the PO. Stock or aftermarket? Truth or fiction?

Thanks for enduring my questions.
