Can anyone tell me if I can connect a Trimble 500 to MT3405F II to variable rate spray - no section control, just VR?

Yep, had a look at that & it seems it should but ..... I haven't been able to get any one to confirm that yet.
If I ask Trimble people they say: "no, you need to pull it all out & fit a Trimble system etc. etc. etc."
Same goes for AgLeader. As usual sometimes you get baffled with BS & all I want is a straight answer so I can make an informed decision.
I could well be better off just fitting a 750 to do the VR I want & forget the MT but info would help.

3 Options:
1: Use existing EZ-Guide 500 with an EZ-Boom and VR Unlock passcode (if doing prescriptions)

2: Use a CFX-75- with Field-IQ & VR Unlock passcode (if doing prescriptions)

3: If the MT Controller has the ability to take external GPS signal, use the EZ-Guide 500 to feed GPS into the MT via RS232 port, and let the MT do the Rate Control - looking at the manual for this controller, I don't believe that this is an option for this model, so you are more than likely looking at the top 2 options.

EZ-Boom's are getting harder to find as they (and the EZ-Guide 500) have been superceded, but there are used ones around (I have a couple).

The CFX-750 can communicate directly with some controllers using the Trimble Universal Variable Rate protocol, but I don't think the MT3405 is supported in this way. I saw what looked like an RS232 port on the back of the display, but there is no mention in the MicroTrak material about it's use.

Yes the RS232 is something I don't know what it actually does, or can do. I've asked MT but have no reply just yet.
So does a 750 have the capability to directly be the controller - get rid of the MT altogether - as well as VR? That would be a better solution if possible.

The CFX-750 can only operate as a spray controller with the Field-IQ switchbox & modules attached, but yes, then the MT controller would go away. You could probably get a loom made up to convert from MicroTrak to Raven or Trimble style connectors and go straight onto the FIQ module that way. You need to be putting the control valve inc/dec, flowmeter signal & section signal wires into the loom at least.

Option 3 requires a third party spray controller to still be there, the CFX just transmits information to & from that controller using the RS 232. This can be for prescription rate applications, or simply to record "As Applied" maps in the CFX-750.
