like the title says i want to know if North american 2007 seats will fit in a 2005 accord thanks and if there's a DiY somewhere on how to do it thanks

 

Those are the same generation accord, so probably. Look up the part number for the 05 and 07 at majestic honda.

I think that you would have to unplug all of the electrical connectors under each seat, then unbolt the seat.

 

You should probably be careful about airbag systems. If your 2005 has airbags in the side of the seat, then you need to make sure the 2007 seats have the same thing.

Disclaimer: My 2003 LX doesn't have side airbags, so I don't know whether they're part of the seat or located in the door pillars or whatever...
