Did you mean the Optronics MCL61AB which we offer as part # OPT66FR? I suspect that the extra white wire you mention is simply an additional ground wire.

To wire the # OPT66FR, you'll need a mounting bracket like # A65PB. The lamp grounds through the bracket's mounting hardware (as long as its mounted to the trailer frame or to metal that's in direct contact with the trailer frame) and the black wire goes to the running lamp circuit.
