replaced steering wheel, rain sensor issues

[j0nblayz]

so i replaced the sport wheel on my wife's x5 with a heated steerig wheel. I also replaced the slipring since the original did not have the plugs for heated steering. However i just noticed last night the rain sensor does not kick in anymore. I dont remember, but on the first click on the wiper stalk, it should still do intermittment wiping right? or does it only wipe when the rain sensor kick in? there was huge wet snow storm last night, and my rain sensor would not kick in or the intermittment wiping did not either, had to keep manually wiping by pushing down. However the second click up, the faster wiping still worked. Any ideas?
