Glad you have the issue resolved.Just wanted to give a follow up, my truck ended up being down for a while for AC repair. After installing the spade connector style ect sensor the temp gauge now functions correctly. Thanks again all for your help!
Tommy to the rescue. 👏The sender in your pic is the weather pac connection sender .It will not work with older gauge cluster. You need the single spade connector that looks like this one made for the 6.2 diesel or similar:

Dont use the part# on one in pic. I think it is for the idiot light. just put it there for reference. Get the sender that specifies" gauge".
. i'm pretty sure it has the same threads as the weather pac type
Just clip off the weather pac connector and use a spade connecter to plug it in.
EDIT Here is the one for a 6.2 diesel with gauge. It is also the same as gasser engines IIRC.
