I don't have a close up picture right now, but I can get you one Friday. I have one that I am working on to polish up.

Here are links to two photos that will get you started.

The main difference is that the thermostat is turned 90 degrees toward the passenger wheel. The hoses on an EFI thermostat housing come out the front or the front bottom where the regular thermostat hose (singular) comes out the top front.

The other thing the thermostat housing has is several sensors used by the EFI for engine temperature. It also serves as the mount from some of the other EFI hardware, such as the cold air bypass.

If you didn't get the thermostat housing for an EFI setup, it sounds like you might be missing several other critical assemblies.
