They are in the points cover...assuming you have electronic ignition. If you have the Yamaha unit then the Lucas one should not be wired up. Zeners also wouldn't be needed, but they are on the back of the alloy air cleaner housing and are probably the 3 pack ones [I think for an '81].
Going on your post, I don't think it would be wise to try rewiring the bike until you understand/work out what you have.
