Your switches, are they POS or NEG output?

Amateurs assume, don't test and have problems; pros test first. I am not a free install service.
Read the installation manual, do a search here or online for your vehicle wiring before posting.

Take one standard automotive relay, switch input ONLY via ignition.
Take output to relay 86.
Ground to 85.
12V+ constant fused at whatever amperage the kit suggests to 87.
Output to heater from 30.
Notes:-
You must ONLY feed switches from ignition circuit, either ignition switch, fuse box or heater input. If you don't you will drain your battery plus possibly a fire risk.
One relay per seat.
If the kit has one fuse, say 20 amps, then feed 15 amps to each relay
