The white wire sends power to the turn signal switch. The pink and purple wires send power to the rear brake/turn lights. The dark and light blue wires send power to the front turn signals.Here is an update to my not having any brake lights. I have power to brake pedal switch and power coming out of white and and pink?(the 2 that power the brake lights) wire on turn signal switch on both sides of that connector. However the brake and turn signal lights do not work, front or back but do have both rear and parking lights working. I am stumped as to what to look at next. Any suggestions would be appreciated.
