I'm trying to replace the ignition switch with a toggle and a momentary switch.

There are two connectors that seem to go to the ignition switch. One is a black connector with 12awg red and orange leads, and a smaller green lead. The other is a blue connector with brown, red, pink and yellow leads, all 12awg.

I know both reds are +12v and connecting them to yellow will crank. So the reds will feed the supply side of the toggle, and the momentary will go between load side of the toggle and the yellow lead. But which of the other leads need to be connected on the load side of the toggle? All of them?
