I have GT 2554 and I did the same thing, went to Auto Zone picked up a 20 amp flush mounted switch with a pilot light, so you know if they are on or off, wired one terminal to a neutral (for the pilot light circuit) and put a male terminal on one side and a female on the other and just interupted the line going to the headlights that is mounted on the underside of the hood and was done. Maybe it took 15 mins.
