Temp/Pressure Sender Installation

[Bluegoose972]

I need to install three senders for my new guage cluster, but unfortunately, I have no other trucks or engines to reference for the correct installation location. I'm also starting with a new crate engine (454 Big Block Chev) so I have no hits there either.

#1) Temp. Sender for Water - Where should this be installed? I see a plug next to the thermostat housing, but I read somewhere that it should be in head.

#2) Temp. Sender for Transmission - Turbo 400. Not sure where to install....Any hints?

#3) Oil Pressure for Engine - I see a plug on the left, front side of the engine, under the exhaust manifolds...Is this where this should be installed?

Any help would be appreciated.

Thanks,
Rick
