I purchased the bracket and switch for the back-up beeper without the beeper. Go to Messick's parts site:

. From there go to OPTIONS and then find the Beeper option.
The parts diagram is there and shows the back-up beeper parts. I purchased the switch $25.36 #K7591-96450, the wire harness $16.15
# K759-96420, switch plate $2.18 #K2581-6220, switch bracket $ 7.57 #K7591-96410, stay bracket $7.57 #k7591-96460 $7.57. Installation was easy.
I decided to spend the money on the wire harness since it had the connector for plug & play and was the correct length. You can add the bolts, etc to be sure you have the correct lengths and sizes. The back-up light is fantastic. Good luck.
