I have a pre-98 trunk lid on a 98 SVT. When I wired the the trunk lid up the license plate lights never worked. After being pulled over for the second time in as many nights, I have decided to wire them directly from the taillights. There are three wires there, a black one, a orange one w/ white stripe and a blue one w/ white strip. Which wire should I tapp into to make sure my license plate lights are on when I turn my lights on?
