i managed to get mine for 112 on eBay for my 240sx/s13. it came with the side mirrors, and the harness/switch with the additional folding option on it. yeah i'm gunna have to do a relay i guess

and run wire out. I think the info in the scanned service manual is for the Australia version, and i couldn't find info either, but that gave a better idea on how the mirrors/USA modelwork

..
Not sure when i'll have time to get this installed, just got an X-Box for my bday, and a desk. which needs to be assembled LOL "that alone will take 5+ hours" HUGE desk. i'll post soons i'm done.
