Got an American Autowire update but they don't offer fan speeds??

[smoknbarrels]

So I updated my '67 C-10 with the AAW update kit, but they only offer a high speed for the heater fan (I have no A/C) and my truck has the 3 prong switch for 2 or 3 speeds, anyone know how I can keep the 2 or 3 speeds? Or should i say - add it to my system, I really don't want just the high speed only.
I've never ran the truck before, so thats why i dunno if its 2 or 3 speeds, i still have the old resistor mounted on the heater box too.

How does it work? Is it just a simple loop to the resistor somehow?

I just finished an AAW classic update install on my 70. I had to re-use the wiring that went from the resistor back to the heater controlls. I had to cut the connector off the brown wire on the AAW harness that feeds the blower motor, and butt connect it to the brown wire on the old harness. I was very pleased with the kit with the exception of this. For $500 bucks, you would think they would include this small amount of wiring to allow you to have blower speeds.
