Motion detector wiring help

I have two 2 bulb fluorescent fixtures that are wired to the same switch. I got three-wire motion detectors to wire into each fixture. The motion detectors are hi bay/low bay sensors that are supposed to be wired directly to each fixture. For the life of me, I can't figure out how to wire these properly. Currently, they are wired in but do not turn off with no motion.
I attached a couple pictures of one of the fixture and a wiring diagram that came from the motion sensor.

What's currently wired:
Black-sensor to black-fixture to black-ceiling
white-sensor to white-fixture to white-celing
red-sensor to red-ballast to end of bulbs. (originally, the red ballast wire ran to end of bulbs with a small wire connecting the two bulbs.

Any ideas? I tried following the diagram the best I could, a video online, and my general knowledge of circuits to wire in a switch. Can't get it to work.

Hi, red sensor wire goes to the Black of the ballast, leave the Red fixture wire connected to the sockets, it does not connect to the sensor.
Black from sensor connects to the supply black only.
White supply gets connected to the white of the ballast and sensor white.

Black sensor goes to black power only, not fixture black.
Red sensor goes to ballast black.
White goes the ballast and power white.

Hopefully your sensor was not burnt out by connecting to the ballast red.

Thanks guys. I'll have to try this later this evening. I don't think the sensors are burned out. They've still been trying to switch.

Your sensors use a relay. They'll be fine. It's your ballast that may be fried.
They don't like to see 120v on the red tube wire.

I tried rewiring it as yall described. As i was rewiring it, I realized this was what i tried first. It still wouldn't work. I took out the sensors and plan on doing something else. Probably just additional lights with built in sensors.

Thanks
