I ordered and have received a headlight switch to replace the one in my 1990 full size Bronco. The problem is, the switch that was delivered is not compatible with what is in my Bronco and the supplier argues that it should fit. Here is a picture of my switch:

As you can see, they are quite similar, but have two noticeable differences: (1) my switch has nine electrical terminals and the delivered has eight (some in slightly different locations), and (2) the plastic housings are keyed differently, meaning the delivered switch will not physically plug into my harness plug, shown here:
Has anyone run across this problem when trying to replace this switch? Anyone know where I can get the correct switch? For reference, the part number stamped on my switch is E7TB-11654-AC and the part number that the supplier says the delivered switch is (it's not stamped) is E7TZ11654B.
Incidentally, the supplier has not replied to any of my concerns (via email and phone) after Wednesday when I emailed them these pictures and described the problem.
