Here’s what i’ve used KaupoiMOD PCB v2.0 - #10 by Kaupoi
From top left corner:
-SP2110 7 pin round connector for autosteer button, workswitch and steering wheel encoder. 1 empty pin.
-SP13 4pin round connector for WAS.
-On/off -button with led.
Lower row:
-Strain relief 12,5mm, USB cable.
-Strain relief 16mm. Superseal plug 4pin. 4 wires to hydraulic valve or steering motor(2 wires to motor, 2 wires to autosteer switch).
-Strain relief 13mm. Superseal plug 2pin. 12V in and ground wire.
If using 12v to 24v converter, I’ve just drilled 12mm hole to the box, and pulled wires through that. Some shrinking tube for sealant.
