I may have screwed up cutting out the 12v wiring but I read multiple times that a majority of the cars are at least pre wired. If not the wiring diagram is attached and will need to be wired through the dash and will be a pain in the ass but likewise would have been a pita to follow and and pull out the whole loom so that’s on who ever wants to install them next

Hi there. Very nice read. So the 9148513 harness runs from the yellow plug under the ash tray to the switches?
Also how many connectors are at the rear seat? I've found 2 on mine, I've also got the 2 rear heated seats switches but no realy, harness or pads.

Any idea where I could get my hands on the remaining items? It's for my 1995 850 T-5R

It would have been a nice option to have had, but never seen one till now.

The unicorn joke has been a heated third row :P
We've seen these, but they are rare.
It’s real. I’ve seen the relay..

Much of my time during the job is spent hauling things up and down the stairs to the basement or in and out of the storage shed, or running back downstairs when I realize I need something else,or taking a break from standing out in the sun,or using flashlights or work lamps when it gets dark.
