I'm tying to figure out how to wire up these euro SPEC tails and read that you can cut a loop by the blue plug inside the car and tap into that. Do to the wonders of Focaljet, when I search for that post again it magically disappeared.Without tearing everything apart what's the deal? I need to rewire for the brake lights or running lights? Do I really have to go all the way to the hazard switch? Sounds silly.
