My girl has a bone stock 2005 altima s. I recently acquired another 2005 altima signature edition with a blown motor. I want to put the steering wheel controls, power seats, power mirrors... etc into the first one. Could I plug and play every thing. use the harness from the sig car and install it all into the s? I did do a search first and most things I read were after market radios. What would it entail? Any and all help is appreciated.
