A jumper wire between the two wire ends in the head light bucket is all you need, from the switch one wire is green with a red stripe,the other is green,both are male ends. Make a jumper wire,male end + male end for the green wire with red stripe,about 4" to 6" long
and find the wire coming into the head light bucket from the main wire harness,green with red stripe,female end,and connect that wire to one of the green connectors.
Works for me. Head
