I'm sure this is on the archives, but right now the search engine doesn't seem to be working.

I just rebuilt the foam and such on my front seats (thanks to the 3M 77 adhesive tip and a couple of old fishing T-shirts), swapping left-right, etc., and machine washing my cloth upholstery. I straightened out the seat heater wiring with some duct tape and glued a piece of cloth over the heater grids so I wouldn't feel the hard plastic grid underneath me.

So now they're back in the car and feel wonderful, like new really. But the seat heaters still don't work (never have). I noticed that they have a few different connectors. There is the two-prong connector that gets connected to the wiring coming from under the carpet. That was what was hooked up when I took the seats out. Then I noticed that there is a black wire and a red wire coming from the bottom grid and the seat back grid, respectively. One is female and one is male. When I took the seats out none of these connectors on either side was hooked up to anything. Has that been my problem all along? It seems pretty clear that in order for the system to work, they need to be connected to one another (or something else), but I hesitate because it's sort of counter-intuitive to hook up a red wire with a black one. Are these two wires supposed to be connected to one another?
