I posted a new thread regarding the illuminated rocker switch for the strobe not actually lighting up inside the cab.
But I can update the OP here about the strobe install:
I ordered the Kubota Strobe Kit for the 1100c. The kit includes instructions. First you affix the strobe light to the metal mount in the kit using 3 bolts. Then you remove the rear center light cover on the cab. Underneath the plate you remove, you will find the black/green-yellow wires. Connect these wires to the wires of the strobe light. Then use the existing bolts to mount the strobe light and mount to the cab. Finally, you install the rocker switch in position 4 or 5 of the switch panel under the radio. I had to cut the tape bundling the accessory wires to release the black/green wires needed for the rocker switch. The strobe light works great, except the switch does not illuminate for some reason.
