Hi y'all I'm currently pulling parts off of a automatic transmission 2006 Acura TL and one of the things I am switching is the seats. I want to go install the 06 seats into my 2004 manual transmission TL and notice that the wiring harness for the driver seat is missing one plug I'm just wondering what The plug does and if it will matter once it's installed.

04 seat

06 seat

 

That's connector "C903" and it is for seat position sensor, and it has something to do with SRS (airbags).

No idea why 2004 seat is missing it and how it affects the system.

 

I was under the impression that just the yellow wiring was for the airbag everything works normal on the seat I just have to check the heated seat function and see if the cars throwing any codes tomorrow thanks for the reply!
