The electrical connectors or the hoses? The electrical connectors are in the harness that runs around the top front of the left side head. The hoses from left to right as pictured are the small hose from the expansion tank, the upper rad hose, the coolant pipe that runs up the front cover, and the coolant pipe that runs along the right head front to back. Can add a picture when I get to work

I figured I’d be able to find one partially apart. Nobody’s working on a 3.0 today. I hope these diagrams help

I did some digging to see if I could help. I found the factory service information and some diagrams for the Q50 3.7 VQ37VHR, but before I point you in the wrong direction, what year and model is your car? Also, if you can post a picture of the loose hoses still in the engine bay, especially showing where they’re coming from, that would make it a lot easier to match them to the correct connections on the thermostat housing. I’d rather help you get the routing right than guess from the picture of the housing by itself.
