My only concern with that is the electrical system already has a lot of strain with the plow.
I think my alternator is only like 60 or 70 amps. I think a PSD has a lot bigger alternator than my 88.

3g alternator upgrade.
1993+ trucks have the 130a 3g stock.
(it's been said,there may be some '92's mid year with them.if your '92 has a serp belt.you have the 3g.otherwise search for the mod.)
The electric fan will probably rarely run so its really not that big of a drain. I got kinda burned out on electric fans after I spent about 400 on some kinda monster flexalite fan on ebay a few years ago and all it did was fall apart. I had cheap allen set screws and the blade would fall off and then got where I could tighten or loosen it. I suspect though like some people on here using factory electric fans the quality is alot higher. Just kind burns me that I spent so much. The controller that came with it also quit working. I will probably do that electric fan mod down the road but using taurus fans or something. I like the way that is all molded into the factory shroud so you can just bolt it in when your done and make it look all factory.
this has been beat to death through my searches as well.
they won't hold up.stick with the OEM ford e-fans from 3.8l cars/vans.
for the controller iv also discovered them to be problematic.
google:
Delta electric fan controls.
i scored the windstar fan and the DC controller for less $ than autozone wants for the stock clutch.
on another note.
i have found the small fan pushes just about the same as the big fan in that windstar assembly.so im not doing the "dual large" fan mod he did in that article.
using this variable speed controller,im predicting based on my temps,to only use approx half this speeds fan at most.i'll know shorty.with the Holiday and everything,i wont get anything shipped out until like monday.and the DC controls claimed 10 day backup on their site too.so it will be a couple weeks.
when i need to plow again,all i need to do is slow right down to 20 mph or just pull over and she drops.so i'll just be careful and watch my temp gauge (a real one.)
