So on my 2018 Ck3510hse I have the bullet style plugs on the right but on the left I have different plug. This plug doesn't have power. Now looking under the cover on the left side of the steering wheel I found 2 more bullet plugs blue and black that arnt capped . I looked in the fuse box and there is a place for optional beacon light relay and a fuse also. I have more switch spaces on my dash. So I guess my question is I'm wondering if these wires are all part of the optional beacon and if they can be used for rear work light.
