These are the cables I have. The capacitor has 1 long and 1 short leg.  What leg is the positive/negative prongs.

If following proper electronics convention then the longer leg is +ve.  May also be a '+' symbol on the body, or a strip with '+' symbols, or a coloured strip with a '-' symbol.

That help?

If you get it wrong it just goes pop!  :-[
