My reply to all was rejected due to as "attachments", so here is what
I said hopefully w/o any stinking attachments.

I've had good luck cutting the long skinny coolant hose that has the
one big end over by cylinder #4 and I think the other end heads
towards the water pump or close to it.  I added a simple  brass T
fitting with maybe 1/2"  or 3/8" or 5/16" hose barbs on it and
whatever NPT thread
pitch your sending unit has.  I think I did ground the brass
connector to make sure it read properly.  I figure that coolant hose
gets as hot as any of them.  Our NAPA store sells VDO temp sending
units for like $13 each in a variety of sizes.

The rest of the installation is up to you.
