Well last night I easily found the sensor (Thanks everyone). The plug
was quite dirty and seemed loose. The sensor had dirt down where the
contact is. Its pretty tight working on it since the big wiring
harness is so close.

I cleaned up the plug and contacts and pressed it back on. However
it seems as though there was no click or snap and the plug was snug but
definately not a real tight fit. I am thinking that the postive
retaining aspect of the connector is maybe broken or worn out however
the gauge worked perfectly. I'll keep an eye on it.

Napa has a pigtail to replace that connector if the tab thingy
is broken. Don't know the number off-hand. You might also be able
to use a couple of zipties to hold it more secure.
