Cummins ISC wiring diagram needed, specifically for the CAPS connectors

[ok-rver]

I have access to the Cummins Quickserve site and have reviewed the diagram 3666267-03 they have available. I did not see any wiring/connections to the CAPS system. Wondering if any one has a diagram that would show any of the 4 pin connectors used on the pump.

2004 8.3 ISC

Injection Control Valve on the side plug?

that's probably one on the connectors. located under the pump. not the accumulator connector on top

Ok I didn’t see where you mentioned the plug coming from accumulator, sorry, ICV is also 4 pin. It’s under the accumulator, on top of rotary manifold 
 

The plugs coming off the pressure sensors on top of accumulator. 
 

I’ll look for wiring diagram

looked up ICV and a picture shows that it is the connector I am looking for. the end going to the ECM away from the ICV has a 4 pin square connector. two of those wires appear to go to the ICV.  The other two wires go about 3" to a two pin connector. This connector on my motor home is not connected to anything. I am looking for a wiring diagram to determine the function of this pair of wires and if they should be connected.
