For the sender, go back to the "pick-a-part" and get the sender from the 
car that you got the gauge panel from. If it was an 8V car, then the 
sender is located on the driver side of the cylinder head, You'll need a 
17mm open end wrench to get it out. I don't think the dealer will carry 
these senders. If the sender is not there, you can probably get a new 
one from an aftermarket vendor, possibly Potterman. 

For the wires, I think you are 0 for 3 on your assumptions, but I could 
be wrong.  IIRC, from my pressure gauge install, the symbols mean the 
following. 

"+"                          12V switched power
upside down "T"       This is the universal symbol for ground
"G"                            This is left to be connected to the sender

again, the "+" is for switched power, and the "T" for ground.
