hi..
'yes' is the answer.
they all originally had the wire wire-tied to the sender itself..
since there are pulleys and belts and things like that spinning around
nearby.
why didn't you say what your real goal is ?
very likely the sender and small harness to it are original to that engine.
Almost everyone I've ever seen on a 2.1 looks like it's been there forever.
that won't tell too much about if that very engine block is the original
one though.
it's pretty easy to tell when the heads have been replaced ..
either by the newish appearance of the rubber gaskets ..
or by them being AMC heads.
the other way ..
which is what really matters..
is by oil pressure.
whether the block is the original or not ..
what really matters is how healthy the rod and main bearings in it are.
I thought someone said what Bentley has for a min oil pressure spec...
Couldn't find it just now ..
I would say ..
fully warmed up ( coolant temp 180 F ) 'for a while' say at least 20
minutes running under load fully and well warmed up, with 20W50 engine
oil, oil pressure at 2,500 to 3,000 rpm should be at least something
like 22 psi ..
like that would be minimum acceptable.
you see something like 12 to 15 psi under those conditions... not good.
