bhi DSP module installation in an Alinco DX-70TH with the remote kit

This radio is going in my truck. But before I could do that, I had to install yet another of these superb bhi NEDSP1061-KBD low-level audio DSP units.  This time it was a little trickier, as the rig has the remote separation kit and the control board for the DSP needed to go into the radio head.  This meant extending the cable between the main and control boards.

While I ran all 5 lines to the head, I only used 4 of them and the 5th, system ground, I tied to ground in the control head.  That meant I only needed a 4 pin interconnect in the head.
