The location of the Connection (White 8 Pin) is in the N70 OCP. the 1,4 & 7 Pins are what powers the Homelink Mirror. I successfully installed mine the past weekend.
Pin 1 is LIN_B13
Pin 4 is + 12 Volts
Pin 7 is Ground
You need part A1565405605
Worked in my 2017 GLA 250
Please let me know if this makes sense.
To remove the three wires from the A1565405605 Cable you’ll need a Watch makers Screwdriver or a Large Paper Clip. The front of the White Plug has 16 small holes on its face. The upper and lower rows of holes are where you will insert the Paper Clip to release the Pin retainer. There are two access doors on the top and bottom of the Plug that need to be opened in order to press down on the Pin retainer to complete the Pin’s removal.
Hi Brian, you need a wrench where the mirror connects to the roof, turn to the right. This will twist the mirror and dislodge it. Putting it back in is the reverse.I ordered the harness and a used mirror ofrom a wrecked CLA. I understand how to insert the pins in the correct position for the wiring harness etc, but how do I actually remove the original mirror? I know I need to first remove the covers from around the mirrors, but how do I do that? Once I have the covers off, is it self explanatory or do I need further instruction to actually remove the original mirror? I can probably figure this out, but I am paranoid about messing up the covers or damaging something trying to pry the covers off.
