Dear community.
I have entirely upgraded my m56 to q70. The only thing that is left is the side mirrors part. And as long as 2011 M models did not have any version of turning signals I don't thing there would be a wiring left for that (correct me if I am wrong)
Has anyone so far put Q70 side mirrors with turning light on m37 or 56 ?
And how should I do the wiring to make the turning signal work ?
Thank You in advance

Seems to be there are a lot of discussions on this topic and none of them really answer the wiring. Looking at the exterior lighting system drawing there should be two wires controlling the turn signal on the mirror. One for ground (Pin 19 on the mirror which is Blue) and the signal (Pin 2 on the mirror which is Green) is spliced into the Body control module pin 60 which is Green(Drive Side) and 61 which is Violet(Passenger Side). These are are the same pins used for the rear turn signals.

Bought this from Amazon for $15 and it works perfect on my M56.
I have automatic folding side mirrors now. Every time I close the doors the mirrors close automatically and vice versa.

The only thing is, you will need a good electric specialist to deal with the wiring.

Hey can you elaborate on the other upgrades are. Thank you
