All you need to do is connect two wires, one to the brown wire and one to the Green with a White trace and then connect the other end of the wires to your momentary push button switch.
To test, connect your test light or voltmeter onto one of the glow plugs or busbar, turn ignition on and then push the switch in.
The test light or voltmeter should now light up or show about 12 volts.
I would use a good quality momentary push button switch, the last thing you would want is the contacts in the switch to short together causing the glow plugs to stay on.
If you intend on having this permanently setup with the switch, we can add a warning light into the circuit.
