It goes into a little regtangular plastic box. Like a brake lever for a push bike does. The the box closes and clips to the slam panel.
For extra safety I put a tiewrap around the nox lid because if it opens itll come off I think.
If its lever end in car you have to remove the lever to fit. Its fidly but you can do it. Trim has to come off aswell if im remembering right.
If its latch end it hooks in. Theres little clips that hold the cable on the slam panel in various places aswell.
Hope this helps.
