My indicators have randomly stopped flashing - they come on when the switch (I've got two on/off switches on my paddle shift) - is on but dont flash.

The disadvantage to not building it yourself is not knowing where everything is in the wiring spaghetti. My first guess is its the relay, but being a complete novice to all of this I am open to suggestions... I cant find any obvious wiring faults.

Scrap that - found it and somehow fixed it. Must have been one of the plugs slightly loose...
