Got it all installed today and all's well. You just slide the sensor down the dipstick tube until you've only got about 5" left. It's connected to two wires and you may need to use the dipstick to help push it down the tube. The guage reads around 140 degrees when warmed up which is normal so I assume everything's working right. I put the guage on the floor next to my fuel pressure guage and I think it looks pretty good. Very easy install that way.
I'll try to post a picture tomorrow.......

 

That's encouraging, knowing it's not brain surgery to install at least that guage. I've got the nerfs, flaps and guards installed, and now my next project is to tackle the guages. By any chance, do you know which brand most closely resembles our oem's?

 

I got the Westachs because they are inexpensive. Isspro just came out with a line that matches the Dodge guages very well. Check genosgarage.com. They look pretty sweet.....
