This is a bit difficult to answer since I don't know exactly what wiring you have. In general the harness on the bar might be slightly different. The power wire that Jon mentions is not necessary with the standard control valve since the green/yellow pair of wires can run the standard control valve directly.
If you are going to keep this Accu-flow system for some time, I feel that changing to the two valve system would be a wise move.
