so I had my motor replaced in my 2005 G35 Coupe 6 M/T the shop had to get compatible parts to match the new motor so I have a few extra parts off of the original.

OEM Body Control Module

OEM ECU

OEM Ignition Switch & Key Assembly

I have no idea if any of these parts are worth anything. If they are id love to sell them and make some extra money.

 

I'd check on craigslist to see what the parts are selling / listed for.

FYI, if you choose to sell these items on here, you'll need to create a thread in the marketplace with proper verification photo(s).
