LED's are polarity sensitive. Hook 'em up backwards and they won't work.

There's no point being a pessimist - it wouldn't work anyway.

Simply, if the connectors don't match, you have the wrong kit. They can be made to work, but you shouldn't have to do that when it should be right the first time. LED's are polarity-sensitive, as the previous reply states. A correct (or higher quality) replacement wouldn't have this issue.
