HELP! What the heck is this?

OUI! Busted my back looking for tha thing. Man is it ever hidden. I thought I was looosen my mind, like WTF? I don't have this thing?

My tail lights work, funny I tested it while I was there.

I just lost my fan for the heater. The main reason I put the Dodge back on the road. I'm no electrican and I"M SO reminded of it everytime I mess with wires. LOL (SOB SOB SOB)

My Duster doesn't have wiper delay. Just 2 speeds.
