Worked perfectly on my 2012 Harley Sportster Xl883L.
The product image shows a threaded screw type terminal, but these are solid terminal plugs, product image doesn't show the actual DCPR7EIX, so if you're wondering about that, its safe to order.
The only issue, was a slight defect on the terminal of one of the 2 plugs I bought, one was perfect, the other had a casting issue that I had to sand away.
