1986 ezgo marathon resistor ignition switch

[EZGO3W]

I have a 1986 Ezgo marathon 36 volt resistor cart with 3 -12v batteries being used. I have a light kit that I added and I bought a three terminal(accessory, battery, ignition, starter key switch. I am trying to wire the accessory switch to the lights so that they can come on via the key in the accessory position and th toggle switch in the on position. I am able to get the lights to work when on the battery terminals of one of the batteries as it should but now I want to get the key switch to work properly. Also the yellow and blue wires need to be terminated to the key switch as well. Anybody know the sequence that would be needed for this to work? Thanks
