You can adapt the electric clutch from the T444E (Powerstroke) that is an aftermarket item from Horton.

It requires replacing the 4 bolt flange on the water pump with the threaded flange from the T444E/PS pump

They share a shaft size so the job is not a great one.
This also requires modifying the serp belt pulley to allow the threaded hub to pass through the pulley.
The bolt circle is the same for the pulley to bolt on to the flange.
The rest is some easy electrical wiring to get the unit working.
The controls are either auto from a temp switch in the head or manually with a dash switch.

I have a setup like this ready to go on my 95 dually.

The Horton unit is available through most Horton dealers.
Its about $600 USD and this is for the Horton parts.
The HO water pump must be purchased seperate and the PS flange scrounged up and swapped out.
