Ginger 55, I had not planned to divulge my 'sneaky unhand plans', but as you ask, here's my plan for my KC install, and my reasons, sure I am either going to learn something here or regret letting my plans out
Currently, my boot mounted ice box water is pumped, from boot pump 1, to SC cooler, then flows to front HE, then to second pump, back to ice box. I am going to interrupt the flow to the SC cooler with the KC, so as, to my mind the 'premium' cold water arriving from KC to the SC cooler directly. Basically that's it. However the people I have spoken with, tell me to send and store this 'premium' cold water to the ice tank, and distribute it there after. But I cannot get over, if the water from the KC is as cold as the system will get, sending the coolant water about 7-8 meters of 12mm bore pipe work, back and from the ice box, will only result in the coolant water temps rising above that which the KC kicked it out. However if the ice box is full of ice, well that's another story, but lets surmise it's not at this moment, as that's a Vmax scenario.
I then get into flow rates of the coolant, is KC going to further restrict the existing flow, as BillyCR has just raised, let alone additional pipe joints vulnerable to leaks, will the KC deal with existing flow rate, too faster water flow, will not chill as needed, too slow, SC potentially over heating, or have I got to create a diversion valve, (had not planned to), to minimise the coolant pipework route so as to not restrict the water flow resistance.
I am going it plum it in, measuring the initial and after, flow rates of the KC firstly, if it's restrictive might have to resort to plan B, which I hav'nt made yet LOL, perhaps you guys are my plan B
