I’ve been investigating what is required to control the electronic JD SCV (remote hydraulics) from AoG or one of the OpenGrade/X variations.
@ChrisC has shared a screenshot of the wiring schematic on his OpenGrade github page
Here’s another screenshot from Chris showing other Option lines and possible SCV 2 & 4 control inputs? My connector only has the 7 pins installed (A-D, G-J).
It shows the connections at a 9 pin Deutsch connector. I believe that’s one of the implement connectors at the hitch, which goes to a 10 pin Metripak behind the cab (underneath the back cover). The pins labels for both are the same, eg pin A is 5V source on both connectors.
You just loosen (not remove) the two bolts under the rear fender on both sides to remove the panel/cover.
I’m prepping a test board with potentiometers for both scv #1 & 3 so I’ll report back with those results but in the meantime, has anyone else done this yet?
