I bought a used F700bt off of ebay missing a power harness. So I then bought a power harness for it from a separate buyer. Anyways I now have both of them in my hands and can't get the harness to fit in all the way. It goes over the prongs nicely and slides down a little but won't clip in entirely. It appears to be the correct harness and I am confirming with the seller that it is indeed. When I looked closely at the prongs though none of them appear to be bent but the big prong in the upper right corner is raised slightly higher than the others. Is this why it won't go down all the way or is
