DIY: Partial Retrofit of e90 LCI Seats onto e90 Pre-LCI Vehicle

If you have a pre-lci e90 and want lci powered seats, you may find this guide helpful.--If you've swapped your pre-lci powered seats with lci powered seats, you may notice that it was not just a simple swap/plug-n-play: your driver's side seat will likely have functionality yet the passenger side will be completely powerless. This guide will resolve that issue.


Special thanks
  • to Lemon for providing me with the opportunity to disassemble his precious LCI e90 and use it as a reference. Also thanks for help with installation. Thanks brotha I know how much your e90 means to you. =]
  • to Lorenzo for helping out with seat transport and installation.
Thanks guys, you two should really join the forums. It's a great community.

After I swapped my 2007 base powered seats with 2009 sport seats, my driver's side has basic functionality, but my passenger side was powerless.

In the end, it came down to moving one goddang wire.
