...Sorry to threadjack, but do you guys think it would be easy for me to install the power folding mirrors on my hybrid?
Yes, I think it would be easy. I haven't looked specifically at a Pacifica folding mirror purchased from Ebay but over the years I've purchased several OEM folding mirror replacements and installed them on several cars including my 2013 Genesis Coupe daily driver. For some reason Genesis Coupe did not sell in the US with folding mirrors, but the ones in South Korea did, so I just purchased a perfectly color matched pair off the Internet. In 2013 the Genesis mirrors came with the same simple internal wiring I've seen on all folding mirrors for the past 30 years. Internally they contain a very small D.C. motor, two limit switches and two diodes (one diode per limit switch). The motor and switches are wired in series so only two wires come out to hook up.
To test, simply hook one arbitrary motor wire to vehicle battery positive and the other wire to battery negative (or chassis ground) and the mirror will fold all the way in one direction until it reaches its range limit where the associated internal limit switch opens stopping current flow. Flip the two wires at the battery and the motor turns in the other direction until it reaches the other internal limit switch which opens stopping current flow once again. If Pacifica folding mirrors work like folding mirrors have for the past 30 years, all you need to do is wire in a DPDT switch or DPDT automotive relay that mimics what you did swapping the two wires at the battery (plus you'll add a fuse, of course).
For your hybrid a big issue might be buying a folding mirror from EBay color matched to your Pacifica. If you are mechanically handy just swap the painted housings.
You could precisely duplicate the original Pacifica door switch and door switch wiring but then you'll get into computers and CAN bus which means the function may (likely will) have to be enabled in the Pacifica body computer. The dealer service department may refuse to enable it or may not be able to do so because your VIN number is not one for a Pacifica purchased with folding mirrors.
