variable speed controller for a single speed a/c blower motor

[justanova]

I know this isn't necessarily pro-touring related but does anybody have any recommendations for variable speed controller for an a/c fan motor?



we had to replace the a/c blower motors in my dads 73 peterbilt cabover and the originals are a 2 speed motor with 1 wire for high, and 1 wire for low speed. The only replacement motors are a single speed motor so we have wide open or off for fan speed. I have searched around a bit and can find all sorts of controllers but as I have no experience with such controllers I don't know which ones are good and which ones are junk. I would preferably like a controller with a "remote" mount speed control knob so that hopefully I can put the knobs where the toggle switches that controlled them before are.
