From what one of the members said the Temp Sensor (on the Loop/Filiment type Glow Plugs) just controls the Glow Plug Light while at the same time serving as a ground for the Glow Plugs.
In this thread:
1976 Glow Plug Update but no voltage to the glow Plugs when key is turned on

and a more recent one the stock Relay would not work with the New Style Adapter Glow Plugs.
I am not sure but if you look at the diagram of the Relay there is a Reed Switch inside of the Relay. I suspect that the Reed Switch is OK with 50 amps but not 80.
But, I actually do not know.
Also if he used a Relay from the 83 would he be able to wire the adapter Glow Plugs in parallel instead of series?
If so I think that would be an advantage.
