Seat warmer problem - need help 850 1995

I have a Canadian model 850 GLE with front heated seats. For the past 2 years, the seat warmer on the driver's side was not working. I found this forum (several suggestions were posted) and I decided to have a go at repairing it myself.

I saw two wires, one red and the other white inserted under the seat. I gave a slight tug and the white wire popped out. I reached underneath and felt some foam with a 2 inch hole. The red wire was still connected and I pulled it out. This red wire ended in a terminal plug (a lug with a plastic casing). I found out that the white wire had broken off from its conector. I soldered the end of the white wire back onto its connector. I checked that there was current to the wires by turning the engine on, and then switching the heat warmer on (orange light lit up)and then with a voltmeter which gave a reading of 14 volts.

The problem is now when I plug it back in, how will I know if I have it with the polarity reversed? After all I had to blindly plug it back in; I had not removed the seat. Do I have to pull out more stuff and is it safe to do so in order to connect the wires back? Will it work when the polarity is reversed or will there be damage?

Thanks. Charles
