So the 330ci has 12 pin and M3 has 6 pin how do you attach the six wires into the 12 wires. Cut the harness off the old 12 pin and then splice the m3 wires into the old harness??? Also what functions will I lose doing this. thanks Any Pics?

I thought 12 pin was for mirrors w/ memory, and tilt. And 6 pin for non-mem, tilt.
I dont know what I have but it is a 04 330ci with power seats and memory. I ordered the m3 mirrors that supposedly keep all these functions hoping it would just plug in?
