    Default 7220 with one system

    Looking for a diagram using 7220 ignition box, 8982 start/retard controller to retard the timing for the nos and the start retard, a 8950 RAS, 8737 3step, and 2 8961 relays. I am wanting to turn the nos solonoids on and retard the timing, at the release of the trans-brake button. Any help greatly appreciated!
