im not trying to be a dick about it I know from first hand that its not an issue with the error cancellor its the way the headlamps get power. The relay harness lets them get power from a solid 12-14 volt source which is needed to keep and hid running. the headlights on deceleration see only 9volts something Ford did to cut back on gas useage during decel.
