I installed a new temp switch and connected the wire, and still nothing. What would be my next move to fix this gauge? Also I have an unconnected wire that looks just like the one hook to the temp switch on the block, this wire is up by the fire wall ( under the hood) on the passenger side of the car could this be the wire I need connected and where should it be connected?

I found a single wire sensor with a single dark green wire going to it for the gauge. Do you see one of those?It shows it right above the starter. Let me know what you find.

In your last post you mentioned your 350 doesnt have a fan on it. Open the hood and look at the emissions label it will tell you what size engine you have. Let me know.
