I have a new/unused Summit Racing heater. Looks a lot like this one, though mine has been sitting on the shelf for several years, so there may be minor differences:

The mounting brackets and wiring harness is there, but not the switch, so you'll have to figure that out yourself or just order the Summit kit...

Summit wants $149 for the heater, I'm asking for $100 shipped to your door.

On the plus side, if that falls through, I did find the wiring/switch/manual for the heater in my garage, and it'd be included at no extra co$t...
