    Default 6520 timing retard thru zex control box

    I am trying to hook up my timing retard on my 6520 6al plus digital box to activate when my nitrous activates. My nitrous is controlled thru a zex box that works off of myTPS switch that only puts out 5 volts and I need 12 volts. Can you help me out?
