My water pump (a Stewart Racing EMP-16143) has two fittings on the pump body. One of these goes to the bottom of the surge/overflow tank. You can see it in the pictures of the tank a few pages back (on page 3).
The heater (heat source) goes to the discharge fitting on the block and the return goes to the second water pump suction fitting on the pump body.
The valve allows circulation from the block back to the pump when the heater valve is closed. It's actually a pretty slick design.

The wiring looks good because of all the new sheathing around it. Honestly, while I don't mind doing electrical work, it takes me a LONG time to do it, because I always get myself confused....
It takes me a lot longer than it should - maybe I don't do it enough!
