Pretty easy..i unplugged that relay on fire wall..then took the 2 distributor wires slots 4 and 5 on the ign brain connector and spliced 2 wires directly over to the sigle p/u distributor...fired up my fresh rebuilt 440 .060 over ...finally got it running....then i had an extremely lean 650 avs...swapping that out for 750 1971 avs..good to go.......More torque than a stinking Belly Button 6.1 they keep advertising lately.,thanks..Jeff
