I have a soft cab and heater for my 3320.
Where can I plumb to the engine for the heater hoses?

I see people using aeroquip quick-disconnects on the hoses.
Wouldn't hydraulic connectors work just as well?
I have lots of them laying around.

Thanks for looking.

John Deere - Parts Catalog

Anyone know what size and threads are on the plugs #24 in the diagram in the above link?
Are they 1/4", 3/8", 1/2" pipe thread?

Your JDparts link didn't work but I think this is the #24 you referred to BUT JD shows no PN so I have no means to cross reference the part. I'm guessing fitting(parts key #40) is what you need.
MIU10723 Hose Fitting ADD 19.10 USD
2nd photo is titled RADIATOR, HOSES AND FAN SHROUD (CAB)

the link didn't work, but on the thermostat housing the allen style head plug is 3/8 pipe. I've done both a 3320 and 3720 with 3/8 fittings. Use that for your hot line connection and just "t" into the lower radiator hose for the return. I believe the lower radiator hose is 1".

Here's a couple of pics from mine. This is of a 2305 but it might give you an idea of the location.
