I had to use a Suzuki switch on my 72 xs because I couldn't find a replacement original one,The yamaha one has 8 cables and the Suzuki one has 10 ,it was a faily simple job to find out which ones were not needed ,I just cut the extra ones off and connected the rest to the existing harness .I think the ones I cut off we're probably the self cancelling turn signal ones and the headlight pass one .
