How To (in progress): Add Climate Seats to Coupe Models Without Splicing Stock Wiring

Ghostvette

Interesting. On the 2012 that I had, the connectors were already in the car, all I had to do was install the relay in the correct spot, install the fuses, bolt in the seats and plug in the connectors. It's possible that since yours is a 2009 7AT, they might have decided to have one wiring harness for everything but the NISMO, then a separate harness for the NISMO. I know on the NISMOs, you have to do what you are doing to add power seats, since the connectors aren't there. Is it possible you have a NISMO?

My car is 2009 Base + Sport, No Nav option.

I have the FSMs for 09 thru 14 and If I remember correctly from looking at the wiring diagrams there were some slight year to year changes in what harnesses were included on different models. I can say that for mine I definitely have nothing. The spot where the climate control relay would be in the engine bay box I have an empty hole

Did yours have the connectors for the climate seat switches in the center console too? I thought heated seat and climate seat switches used different connectors.

I remember the connectors for the switches and the seats, but at the time, I couldn't afford the cost of the seats, so I didn't get too far into what went where. Mine had the connectors for the switches bundled together under the console and the seat connectors were under the carpet. That car went to automotive heaven in Aug 2018.

I used a flashlight to verify terminals in the empty slot for the seat relay. If the terminals are there, it should be a matter of putting the right fuse in the fuse block and installing the relay.
