I need to know if the wiring is there for power and heated seats on my second G35 6MT.
I have a 2004 with power and heat, (someone totaled it from behind,) I replaced it with a 2003 with power drivers side and manual passenger. I'd like to trade the seats and heat switches from the 2004. If I just pull out the seats from the 2003 and open the console,
will I find the pigtails I could just plug in to?

 

Most likely not, you'll have to take them from your 04. When taking off the 04 seats, also take out the harness that the seats connect to, you're gonna need them on your 03. To make the heated seats work in your 03, first install the switches from your 04, then you'll have to pull a relay from under the steering column of the 04 and install it at the same location on your 03. If you have the two cars side by side you can compare and see which one it is.

Sounds like the 03 doesn't have Winter package, you might want to swap your heated mirrors, too.

 

Hello,

Resurrecting this thread...

I have a 2003 G35 sedan and I'm putting coupe seats from 06 with heated seats. I currently have manual passenger seat in the 2003 sedan. Will there be connection for the power seats? Will I need to add relays?

 

Does your sedan come with heated seats? If it does then you should not need to add relays. For passenger power seat controls, I'm not sure if your car's pre-wired, however you can check under your passenger seat, besides the airbag and seat belt sensor hardness, if there's an unconnected 4-pin wire harness tucked under the carpet, then there's a great chance you can get your 06 power heated passenger seat to work. If not, it'd be difficult to add those functions.
