There are 4 wires to change according to the manual. One for horn, one for hazards (pink), and 2 related to turn signals because we are not using a dash mounted switch. Sounds like its the last one that you might have missed. You need to seperate yellow and white front turn signal wires from the green and blue rear turn signal wires where it goes to dash switches on the roadster. Its in the main HR manual just before the fan wiring section
