Any other reason for wires under a seat?

Probably the stupidest question this month/year but I'd rather be sure.



A guy told me he has ZS seats to flog, but doesn't know if they're heated. I asked him to check if there's wires underneath - he said there's 2 plugs, and 4 wires total.



This can presumably only mean they're heated then I assume? I'm not sure if seatbelt tensioners or airbags or something similar could be in some way related.



cheers
