HID light help needed. Any experts out there.

I bought some new headlights for the excursion from amazon, which came with the cheap Chinese bixenon 35w HID lights. Install was no problem the lights work but I dont get any high beams. This is a 9007 bulb and I changed all the pin combinations without luck. When I switch from low to high the lights are momentarily brighter then return to the low beam brightness. I'm wondering if the ballusts arent getting enough power from the OEm harness and need to direct wire from the battery.
