Update: I visited the local Kubota dealer today and they said the two 4-pin plugs under the instrument panel are for the OBD diagnostic tool they use...so don't touch it! FWIW, they also told me the 4 cavity/5 wire plug under the left rear fender is for connecting to a trailer.
Congrats on the L47. Not sure if this is what you are asking but rear remotes are often used with a hydraulic top link, a Top & Tilt, and/or implements that are more complex (seeders, spreaders, etc).
Hi - recently bought a MX5400 HST and realized I should have had the dealer install the rear remotes before delivery. Now I will likely do it myself but looking for spare electrical connectors I can tap into. Came across what appears to be two unused connectors directly underneath the driver...
