Hard wiring heated Wet Okole covers

I know this has been discussed before, but I've done a search and have not been able to find an answer to this. Has anyone taken a heated Wet Okole seat cover and hard wired it? I've seen posts where owners have taken non-heated covers and installed a heating kit they purchased off of Ebay. What I want to know is:

How did you make the connection between the existing heating pad and the switch?

Are there suppliers that just sells the switches and harness? I'm thinking I may have to just go out on Ebay and purchase one of these kits, but discard the heating pads.

Did you end up buying the kit and discarding the pads? How did it turn out?
