I got one and canabalized it for my simplified harness. Got rid of the 31 yr old wires and was able to keep the correct colors. It fit fine to my bike and has all the correct conectors, but like I said I cut it up.
Make sure you get the correct harness. They go by the first 3 characters on your VIN. Example: I have an '81 SH, so the VIN is 4M4-XXXXX. There should also be sticker on your harness with the number. I think it's near the coil.
