I'd say to go with these:
115-0171-938 chassis power cable for row crop tractor, mid battery
115-0172-001 Envizio Pro console cable

Then, depending on the type of master switch you want to use, you can get these:
115-0172-075 Foot switch extension cable
063-0173-080 Foot switch
You could always build your own master switch and connect it to the REMOTE SWITCH plug instead.

Finally, for an extra GPS antenna and cable:

115-0171-787 15' Envizio Pro GPS cable
063-0172-651 MBA-6 GPS antenna

I don't sell on here, just visit your local Raven dealer instead. You'll probably want them to go over what I've got down here just in case you have some special circumstances.
