Re: Race ignition (05 GSXR 1000) to oem
Power from the O lead of the ignition switch runs to two places, one of which is the START button. It leaves there as W/Y, which runs to the HEAD-LO and HEAD-HI fuses. HEAD-LO leaves as W to the big connector inside the left front fairing, where it changes to B/Br, which runs to the low beam. HEAD-HI leaves as Y/W to the dimmer and passing light switches. It leaves them as Y, which changes to B/Y at the big connector, which runs to the high beam and the cluster's high beam indicator.
So what you need is going to depend on exactly what you now have. And, like Yngve, I can't tell from your description. Sometimes racers just remove things in the front harness. More serious racers also start chopping up the main harness, but they also tend to replace the ignition switch. We need to know significantly more.
P.S. The Br lead from the ignition switch is for the turn signals, position lights, license plate light, and tail light.
