Just send it to ag express and have them fix it. A 450 is just a 440 with 3 additional boom switches.
Yes, essentially. The programming and keyboard are slightly different to allow for 6 sections. The 450 uses the same wiring pattern as the 440 but has 3 more pins for the extra potential sections.
The first thing I would change is to get rid of the Single Fast Close valve and replace it with a two valve system where the control valve and ON/OFF valve are two separate valves. The Fast Close single valve systems have caused many problems and much confusion through the years.
Are they cheaper? Yes. Can they work? Yes, Would I personally use or recommend one? No. I've given this advice many times through the years and have been thanked many times for that advice.
