I added a switch to good ole fuse 11 to disable the ESP on my car. Here was the process if anyone wants to duplicate it. The switch I got from www.dirtyparts.com. The switch cover is part #OTR-VVPZCVS500 and the switch itself was #CLT-V1D1J66B . The switch came assembled and not in two pieces.
First step was to drop the fuse box down by removing the two silver screws at the rear of the box-
Once the box is dropped down unclip the grey connector from the left side of the box. The wire we're interested in is the RED/PINK which is four positions from the rear side of the connector. That needs to be cut and then wires run to the switch-
Wires soldered and heat shrunk on-
Now to cut the hole for the new switch. I made a paperboard template then traced that onto the plastic. The plastic cuts very easily with a sharp razor blade-
The two wires run to the switch pins #2 & 3(order doen't matter) and then clip the switch into place. Tada like it was from the factory this way!
And a youtube video showing the results-
