Water heated intake/Electric fan temp sensor

Hey all you mopar motor heads.I have a couple of questions I need feedback on.I have a Clifford 4bl manifold on my slant 6 which has two water ports to send coolant to a chamber just below the carb to heat the fuel/air mix.I tried to contact Clifford on how to set it up.What a joke!If someone could tell me how to properly hook it up.Then I want to set up a electric radiator fan system I understand the electrical hookup.But the temp sender is too big for the stock sender inlet.My car has a temp gauge which I want to keep any ideas the kit is a spal which I bought from summit.I would really be thankful for any help on this!
