I have uploaded pictures of my thermostat bypass to my Club Cobra photo album. I think I have labeled the photos correctly. The intake manifold outlet goes to the water pump and the thermostat housing outlet (thermostat bypass) goes to the heater coil under the dash board. The heater coil return goes back to the water pump. I think this is the same as Mattpatt described. if you go to my album there is a description of the picture in the name.
