I'm ready to install a Back Off brake light flasher on my 2006 C90T. I have the Clymer book but it does not have a wiring diagram. I do not have a service manual (probably my next purchase). Can someone advise me what color the wiring is to the brake lights? Has anyone installed one of these on their bike and if so, any advice as to the best location to mount the box. I thought under the seat probably. I can use a voltage tester but hope to get a head start and confirm with tester.
