Tomosakis, you explained it a bit better, I didn’t even think about posting or taking pictures while I was working on it sadly. Mines also a 2101. There can’t be many of them made. I was in the exact same boat as you, I scoured the internet with lots of posts of people that either never solved it or solved it and didn’t tell how.
I used the ag leader harness to retain my factory boom switches
CABLE - OEM SWITCH - 7 BOOM (5 FT)
4000527
You’ll still need to jump the wires together whether you use this harness or not to allow the ag leader to control the valve.
Yes, this is the OEM switch cable I was referring to. This is the model that will accommodate 7 Booms. They have another one that can handle more booms, it has two of the black diode boxes that you can see in the picture below.
I still do not understand what you mean by jumping the wires together whether you use this harness or not. The Hagie switches (including a Master) will allow you to give the system "permission" to turn ON the section valves. The wiring from those switches should not go anywhere else. See picture below.
The Liquid Module is the only device that should control the valves. If you cannot get the system to open the valves something is preventing this other than the switches. You must have a target rate other than zero, auto swath OFF, High current Power to the Liquid Module and the implement switch branch jumpered.
Below is a picture of an Auxiliary Module, the special harness that you have (note the black diode block) and my homemade switch box.
