Near Intersection of I-35 & I-90 Southern Mn. | Since you are are going to make some type of switch box anyway, I would make a new one that handles both the Ag Leader functions and also your Air Compressor and Duo Rate functions. In most respects they would still be separate but in the same enclosure. That way you would not use the Ag Leader switch box at all but use this "new" switch box for everything. This is essentially what I did with my first planter.
For the Ag Leader side you would need to obtain a Green Deutsch plug to plug into the Auxiliary Input Module and the correct pins. The switches for the Ag Leader things could be the SPDT type since the Switch Detect pin from the Auxiliary Input Module must be used. Another approach is to use diodes but using SPDT switch is probably easiest to visualize.
The switch detect wire is needed for a couple of reasons: 1) It guarantees the output from the switch will either be solidly Logic High or Logic Low. With a common ON/OFF switch, the output may float when OFF and confuse the system. 2) For brief periods of time, the Switch Detect goes to 12V so the system can determine which of the many inputs you are actually using. That way the system only needs to check those switch locations instead of all the switches that might be used.
The Ag Leader wiring will need a 12V source coming from the module split and go to the lower terminal of each SPDT switch. It will also need the Switch detect wire which will split and go to the top terminal of each SPDT switch. The center terminal of each switch will lead back to the Green plug. The center terminals will connect as follows: F1 (Master), F2 (Left seed), F3 (Right seed), F4 (Left Spray) and F5 (Right Spray). Your configuration can remain the same as before. If you check the diagnostics you should then see F1 - F5 as either Green (switch present and ON) or Black (switch present but OFF). The remaining "F" locations should show Gray (no switch present).
Your other switches for the Air Compressor and Duo Rate can be SPST switches which lead to the relays controlling those devices. The end result is the same as adding a new switch box for those devices but it would all be in a single enclosure without any unnecessary switches.
Many would consider this not worth the effort but I believe you can certainly make it work. Should you wish to explore this approach I can get you the pin locations for the Ag Leader plug.
Here's a very rough drawing of what I have in mind:
