Cab Heater hose location on 3*20 engines?

[OrangeJbird]

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.

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.

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.
