2005 trx 400 ex tail light

i just purchased this quad and the only thing wrong is the tail light doesn’t work and i only have one setting for the lights. I think the po changed the wiring because the lights are controlled by an illuminated rocker switch on the left front fender along with a toggle switch used for the kill switch. The key switch is the only thing on the handle bars. The starter is hidden under the gas tank but easily pushed. So i need to try and fix these two things. I dont have any power to the pig tail for the tail lights but i do for the break lights, where am i suppose to get power from for these? I will have to get a hi lo switch for the lights.
