2000 cherokee hatch latch part number?

The cargo light in my 2000 XJ doesn't come on when the hatch opens. Easy search to find the switch is built into the latch and a common failure, but I can't find a new replacement, only used ones on ebay.

Does anyone have the right part number for this so I can track one down?

Thanks!
