How long do you need it to be? I've ran into this problem in the past, you need the little adapter for the S.W. tach and the matching cable length with the proper tach end for the adapter I may have one,let me know the length you need and I'll check mine to see if it will be long enough Edited, both of my cables are for the Jones Motorola tachs, sorry I must have sold the other cable with the adpater when I sold the last S.W tach several years ago, CRS disease
