I have a 2008 E93 that comes with memory seats. It's pre-LCI. The original mirrors are manual folding and I have the parking feature with the passenger mirror tilting down in the reverse gear. My original mirrors are both 3-pin mirrors, but my driver's side loom has 5 wires. My passenger side loom has 3 wires. Based on what I read, I shouldn't have to do any new wiring. My question is with the new mirrors. Do I need to buy a 5-pin mirror for the driver's side that has a 5-wire loom and a 3-pin mirror for my passenger side?
