Expert Reply:

If you got something like this Adapter 7 Pole to 4 Pole with Tester # 47345 you will be able to convert your 7 pole to the 4 pole you need to power your light # CR-007G, you can also test to see if everything is working. If everything is, I think you may have an issue with your wiring with your factory 4 pole. You may also want to check your fuse box for a blown fuse. Also try to check your factory wire connection under your truck bed.
