Thomas HDX - Anyone know what these relays are for?

There's this series of relays mounted separately just below the left relay/fuse panel, and they're all interconnected in some complex way that's leaving me scratching my head. No mention of them on the door-mounted diagram. I have some loose wires coming from a couple of them that originally went to something I removed, possibly the face slappers, or maybe the webasto, can't remember for sure. Just wondering if anybody has any insight. Thanks!

If they're not on the factory wiring diagram, they're for optional equipment. Quite likely for the accessories you removed. If you can't trace the actual wire, you can test continuity to the wires that would have plugged into those accessories.

just like we do in the phone business when we cant find where a line goes.. we carefully disconnect it , tage where it went, take pictures and wait for someone in the building to say "hey i had this line and now its dead...."..



do the same with the bus... and if something doesnt work as expected, reconnect, and test again... if it works, now you know where that wire went..
