Thanks for the response.

I didn't buy the complete kit just the basic kit. It didn't come with the heater hose or fittings. I just wanted a better quality hose, and I knew I'd be adding the valves, so I figured I'd get all the fittings where I bought those (Home Depot).

Also, I didn't use the three speed control switch that came with the kit. I had a two way rocker switch in the dash that I wasn't using, so I hooked the heater to that. Now I only have control of "high" and "medium" speed. I thought that if I needed the "slow" speed, I didn't really need it on at all!
