There is only one cable on the 69's through the S2's (for the trunk release) unless someone has swapped the B-pillar trim with the later version from an S3 and added the fuel door latch/lock and retrofitted the fuel door with the release. The B-pillar trim is different on the roundtails so it would take some mods to make that work. As Brian mentioned, if there is a cable for the fuel door, all you have to do is cut the trunk cable down to make it work. You can always go to a bike shop (if they're even open these days) and buy a replacement cable/sheath.
