Yes. Just did the Auto Backup Light and Auto/Manual dash switch for the backup light on our '21 P700-4. The kit and harness is of very good quality. It installed per the instructions included easily. Our single light is very bright and makes for a great backup light/work light.
As an observation, and something we did, you should buy about 25' of 1/4" - 3/8ths" black wire loom to encase your new wire. We used 1/4" loom. When under the P700 you will notice most wire is enclosed in split loom to protect it from abrasion. Additionally, most factory loom is also partially wrapped in black electrical tape, I assume to keep the split loom from opening. The loom is easy to install as you tie strap your new wiring to the frame, or main harness. Another thing we did is put a small amount dielectric grease in the connection for the back up plug inside the right rear wheel well. We also dielectric greased the connection of the harness at the panel switch.
I know the thread is old, but there is some recent traffic so I thought this might help someone.
