It's not a route that I would recommend as it will remove the APC protection against knock; somehting that is more likely to occur if, as I suspect, you intend to use the Turbo XS controller to increase boost.
However if you really do wish to do so, then remove the C hose from the APC valve and attach it to the input of the Turbo XS, and the W hose to the output. Ideally, you should then clamp the R hose so no unfiltered air might enter into the system. It doesn't make much odds whether you disconnect the electrical connector.
The letters C,W,R are moulded at intervals along the length of the hoses and the order they are attached to the valve, top to bottom is
C (Compressor output from turbo)
W (Wastegate)
R (Return)
