But if going from 3 to 5 and vice versa, then clearly not.

I retrofitted M3 mirrors back in the day and it was plug n play as I had 3 pin connection
I've got no memory seats, just autodimming.

Pretty sure it'll be 3 pin on mine, and mirrows I'm looking at are 3 pin already.

If it's plug and play that would be great. But from what I've looked up so far the LINBus system is the key. If your old mirrows is powered through LINBus your fine, but if not, than you have to do addtional wiring ...
