Water temp Gauge?

So I got an aftermarket water temp gauge. Its a mechanical one with a sealed gas tube. There is no way to install it and still have my stock gauge work is there, or am I going to get lucky and have an extra port somewhere like when I put in the oil pressure. thanks for letting me bug you guys.

 

So It came to me last night and I dont want to start a new thread, hopefully some on will see it here. So if installing an after-market water-temp gauge and you want you dummy gauge to still look like it works, measure the resistance across the stock temp sensor when it been heated with hot water 160-180 degrees, buy a resistor from radio shack of the correct ohms, hook it up across the unused plug and you stock gauge will should read around normal operating temp.
