Hey guys, went to a car show/ swap meet here in WI.

Got a pair of SS seats in really nice condition for 75 bucks, and i want to put them in my 99 sierra, because my drivers side seat is busted underneath. Now there are two plugs coming out of the drivers seat on the SS seats, theres a small yellow one and a larger harness type thing. Is the smaller one the airbags or something? My 99 seats have that same plug.

Also can i just run power to the SS seat for it to work? Can someone tell me which wires on the harness i need to feed 12V?

Thanks.
