So I bought a used OEM steering wheel for my 99. Mine is foam, so a leather wheel was going to be a nice easy mod. I got it all apart to find out the plug on the wire going directly to the charge is different. This is the wire about 2 inches long and goes from the yellow plug inside the wheel to the center of the charge. The charges are slightly different and are not interchangable. The wheels look almost identical, but the center sections are slightly different too. The one I bought is for an SF, but apparently not a 99. I hope I can find this wire somewhere. Now to figure out what year my new wheel is from...
