you're using momentary switches at the front?
Edit: never mind, went back and looked.
With TAIL wired to AUX, you have Brake wired separately too? If you are using and LED tail light, you can use a single wire configuration by wiring only through BRAKE (see 7.8.1 on page 10).
To activate/deactivate HAZARD, it should only require holding L/R buttons for 2". If yours is misbehaving, I think somehow you have the MENU setup wonky. Do your indicators function properly under normal operation?
