HELPFUL HINT: Instructions mention NOTHING about small tabs [clearly seen in attached photo] extending 90-degrees from 3 prongs in back of headlamp. I surmise tabs help keep wiring harness snugged onto headlamp's prongs. But those tabs sure make it HARD to remove, and install wiring harness. You just have to keep finessing it until it comes off, or goes on. HEADLAMP works great!  P.S. Those "tabs" are pictured in diagram on box, but are never mentioned in the Instructions text as to what they're for, or how HARD they make it to plug in wiring harness. I even watched a YouTUBE video on DIY installation-- the guy just plugged in wiring harness effortlessly!  Not sure how he did that w/ a tab sticking out at ninety-degrees from each prong!  With patience and a lot of elbow grease, headlamp did plug in, snugly.
