Temperature Guage help

["James LaLonde" <deloreandmcxii@xxxx>]

I just got done checking my fuel pump circuit and ended up replacing 
the fuel pump... I was stuck on the side of the road, so I had 
checked both the inertia switch and the pump relay. both of which 
eneded up being fine... as once I got home I found that I had power 
at the pump.

But I get everything in the rat's nest behind my passenger seat, and 
everything under the dash and at the pump put back together... but 
now my Temperature guage is pegged straigtt down. Apparently my 
coolant is -80 degrees... perhaps that's too cold :P

My thought is that's it's either come unplugged at the sender or at 
some point in between. Looking at my miniscule wiring diagram it 
looks likes it's gounnded right after the guage... am I reading that 
right? Where is it grounded? And where is the sender? Is it the one 
on the block on the passeger side near the hot water valve?

Any suggestions on where to check? what to do?
thanks!!!
