I don't have a detailed diagram of a 88 switch, but I do for a 86, and it will take a double pole momentary pushbutton switch for the starting function, and one double pole single throw switch for the run, or two single pole single pole switches.

In 86 the power comes in on two large yellow wires.

The momentary start switch should have 4 terminals. Two will be shorted together and hooked to the yellow wires, and one of the other terminals will be hooked to a red/blue(start) and the other terminal will hook to a brown/pink(resistor bypass).

The toggle switch will have 4 terminals also. Two will be shorted together and hooked to the yellow wires. One of the other terminals will connect to the red/lightgreen(ignition and other stuff). The other terminal will hook to the black/lightgreen(accessories)
