seb, its easy, when i had my wing indicators smoothed,i went under the bonnet and got someone to pull on the indicator wire from where the indicator was, found out which wire it was tugging, and then simply chopped it and ran the new wire through the hole in the bulkhead where your amps would go, then through the connector in the door to the mirror base plate, although i have no arch linings due to the wheels scrubbing on them, so im presuming this would have made it easier, any q's let me no m8
