I have a Kubota L 285 and I am pretty sure it is not a grey box Kubota. However it is older and I am having some difficulty finding one specific part. I am needing a complete wiring harness. All the parts houses say it is discontinued and I have looked through and called many salvage yards with no luck yet. My question for this forum would be is there a wiring harness out there for a grey box Kubota that would be the equivalent and that would work on mine and that would be available for purchase somewhere. I appreciate all help, this is a great little tractor and I am just trying to save having to re-wire it the old fashion way.
