Hi guys, I've been searching online but can't seem to find any info on installing a 3rd function for the 4m series. I have a 2019 4052m with power beyond for my backhoe. Now, how do I install a factory 3rd function for a grapple? All the info I've got from the dealer doesn't clearly show what to do...So frustrating! Hope someone can help me get to the bottom of this. thanks for your time.
