The following is a list of connectors we have used to create a bespoke wiring harness for  a customer Yamaha R6 in 2008. This was a racing machine using an aftermarket ECU. This list is a starting point for any connectors you may require and it needs careful checking. Your machine  may be a different  spec to the racing bikes we were working on at the time.
