I hope the dealer didn't charge you for that install - if so, print that pic out on a BIG piece of paper, glue it to a board, and slap him with it.
What you can see sticking out there is what was already tucked up under your console from the factory, they've just been too lazy to fiddle it back into position so it doesn't show. Undo the 3 screws holding the console onto the tank, lift the console, and tuck the plug & harness up into the side of the console beside (or in front of) the tacho. Make sure none of it's sitting below the tacho, or it'll try to push out of the console. Then carefully replace the console and it's 3 screws making sure the harness stays where it belongs. It's a bit fiddly but not too hard.
