When I gutted the interior of the M3 I had to find a new home for the combo door lock – emergency flasher switch. I originally used some Gorilla tape and stuck it to the shifter console, but it didn’t hold up to the 90+ degree days of summer. So I decided to fabricate a bracket with my 3D printer.
I found a CAD file to hold a BMW OBD II port and resized it. It turns out this switch is 93% as wide and 150% as long as the standard OBD II port.
I attached a couple of riv-nuts to the console and bolted it up. I may need to reprint it in ABS plastic, but lets see how it holds up.
