Can anyone tell me what this is? I found it wrapped up in a bundle of electrical tape (like everything else so far) and have no clue as to what it is for. The little black box plugs into the "card". I've lost my turn signals so far, although I have some other stuff unhooked. Does anyone have a wiring schematic they can post or email me that I can print out? I hate not being able to trace sh!t through wire looms.
