Leather seats

Shouldn't be a problem. Only thing that may not be available is the power plug for the power lumbar switch and heated seats (if you don't already have it). I just took a look at mine and the power lumbar goes from the switch, back down the side to the rear upright, then disappears. Too dark, hot, and humid outside now to take apart the seat to trace it out. Going into the seat from the main power harness, there's three plugs. Yellow for Airbags, 4 pin white plug, and 2 pin white plug. I have the model 4 w/ heated and power lumbar leather seats. Hope this helps.

 

Funny you should ask, @Steve Bachman was just asking about that a couple of weeks ago.

Take a look at this thread:
Can OEM leather heated seats be swapped from a 2010 V to a 2010 III? | PriusChat

I just did this search on google.com: seats swap site<colon>priuschat.com
( where <colon> is : )

Wow! The number of threads related to this topic is off the chart!
