Swivel seat electrics.

Hi Guys, I’m trying to fit my new California seats into an older van but I seem to missing some connectors on the seat.
The old seats had air bags and heating elements and the new ones have the same but there are only two connectors on one seat and one on the other. None of the connectors are the yellow air bag ones and I was wondering how many connectors were under your seats?
The seats are out of a 2014 van so anything around that year would be great.
Thanks.
