I just came across this site as I was researching how to install an aftermarket cab heater in my 2005 John Deere 317. Specifically, I need to know exacly where to tie into the engine for the coolant supply to feed my heater core? If you have any pics that would be very helpful along with exact specs on the parts needed to tie in. I have everything wired and the heater hoses run back to the engine compartment, so I hope you guys can shed some light on the rest as my dealer has no idea and does not have one on their lot that I can look at for a reference. Thanks in advance.
