Default Temp sender wire bypass

Is there a way to bypass the junction box for a 94 cherokee? My temp gauge is pegged at max and a mechanic I know said its an indicator of a short. Instead of replacing the wire for the sender and have the problem be in the junction box I just want to bypass it to make damn sure it works. Any idea if power is supplied through the dash cluster to the sender or will I need to tie in a power wire? Thanks for the help guys.

I'd first try unplugging the wire at the temp switch to see if it bottoms out to verify if it's a short or not.

ok mine stays pinned to the max while plugged in but when i unplug it it bottoms out. i just replaced the sending unit it looks like it could just be dirty on the female side of the plug tho...
