Dash lights and gauges out

UPDATE...

I got everything put back together last night. Broke one pin off of the multi-pin connector, and that only effects the right turn indicator light.

Bad news is, this didn't fix **** except I have all of my dash lights now. Temperature gauge just barely comes up to 120, and gas gauge is pegged on empty.

I thought I might have a bad temp sending unit because when I replaced the water pump, the hoses were clogged up with some crap, I don't know what it was. New sending unit didn't help much. Now it goes above 120, but not to the normal range. Thermostat has been replaced and car is getting up to temperature.

I checked the ground strap at the gas tank and even wiggled it back and forth to make sure it was making a good connection. Same with the sending unit wire. I didn't ground the wire or anything to see if the gauge moves. I can do that this afternoon.

HELP!!!!!!
