I finally got the passenger seat installed yesterday. Soldered in the connector from the donor car and had to install a ground wire and the power wire. The BEC has the power tab for fuse 15 but no output tab. I made my own tab for it and ran the power wire back (what a PITA that was). Had to remove the passenger tire and wheel well to do it. Everything worked in the end with no smoke or airbag alarms on.
