Hi everyone, I live in the UK were we need separate orange rear turn signals like the pevious model style Cobra. I was just wondering if anybody knows how to kill the power to stop the brakelights working with the turn signals as if fitting Cobra taillamps on the 99 till 04 GT or V6. On the 99/04 there was a green wire under the steering colum, cut that and then power your brakelights from the centre brakelight "as it does not flash with the turn signals". Does the 05 have a similar wire to cut ? Any help would be greatfully accepted.
