lol. We all have our wire schematics that look like chicken scratch! I have one for my meth system and one for my nitrous...I have two harnass that I bunch up and kept separate...Based on Scotts schematic I would agree with his chicken scratch diagram...There is nothing wrong with using the VC-25. Green wire from VC-25 indeed should goto pump red wire as this green wire from VC-25 is the trigger to turn the pump on when the desired boost activation is reached....
