I'm in the process of installing a Sunco AcuraTrak hitch and Trimble TrueTracker on my cultivator.  Can anybody offer any tips or suggestions to make the process go smoothly?  I have most of the hardware and cabling installed and hope to be able to start calibrating later today.  I put a mast on and mounted the NAV box to the mast with it facing forward and the connectors pointed down.  Is this a workable orientation?
