Fording Kit M925a2?

[barkster]

I have been searching through the repair manuals looking for these hoses that are run to this top sides of each of my differentials and can't find what they are. I'm wondering if they are low pressure for fording? I don't have a fording lever in cab but do have snorkel and the plug for the tranny. What are these for?

The larger hose is the CTIS supply and the smaller ones are the air brake service and emergency lines.

ah I didn't even think about the CTIS, that's what it is, darn I was hoping I had fording kit
