I recently purchased a new integrated undertail for my 99 RRX, have wired everything accordingly and yet the signals flash double speed. Have tried various resistors.
The suppliers instructions said no need to connect the grounds, so I guess everything is grounded together internally.
Have spoken to the supplier who has agreed to swap the lights over, but am just wondering if anybody knows what might be causing this. The same rear lights are brake lights + signals.
So far I'm suspecting relay, I may have shorted something by accident.
Any help will do.
