I have just installed a hitch to use for bicycle carrier on my i3. I found a danish removable hook with vertical mount that did not need as big modification on the rear bumper as the ecohitch one. :

Fitting was pretty simple, took me 2 hours when i was meticulous.
Next is to do the electrics but i have had troubles finding a wiring diagram.
I will use a transistor box not to draw current from the lead lights. Is there anyone here that already done the operation and have good advices to share? Or anyone know where to find a wiring diagram would be much appreciated.
Thanks! Andreas /Sweden
