NV3550 reverse light switch socket size?

[Sparty]

Hi everyone. I hope to go to Harbor Freight at lunch today and pickup a sensor socket to remove my backup light switch on my NV3550. Anyone know what size I need? Also, I thought it was on the driver’s side but the service manual says passenger side. What side is it on?

Mine needed a 22mm deep well and it was on the drivers side.

On the 2001, the Reverve Light Switch is on the driver’s side and is a the bolt/switch/wiring is a permanent connection to the sensor wiring into the next plug connection (next plug connection is attached to the transmission with a plastic screw clip retainer). I removed the swtich assembly by disconnecting the next connection plastic clip, and then getting a crescent on the sensor switch bolt.

Just replaced mine over the weekend. 22mm is correct at least for the NV3550
