I would say, from the supplied pics, you still have the rain sense module. I suspect the previous owner unplugged so that it would work manually. You can probably plug it in and re-activate the rain sense feature.
The black box above your finger nail, in pic 2, looks like the sensor module. Look outside at the box, through the windshield, if you see what looks like a clear LED (or two), that is the sensor box. I disconnected mine. I pried off one side of the black cover (it should open easy, don't pry too hard) and removed a cable just like the one you are holding. If it is the sensor module, there should be a socket for the plug.douellette said:well where is it supposed to plug into? i didn't see any empty plugs. There is a metal ring on the windshield right next to where the mirror mounts if that helps
Haha, here's your test question, how many times does "red wire" appear on GMTN?douellette said:i do have a red wire unhooked from the engine fuse box..... haha, should it be hooked up?
