That is one of the reasons we did it also. You won't have a problem with this set up. To save you some guess and check time: for each of the presoak use a green colored Hydraflex (.125 orifice). If you have a regular Vector, you will need .083 injectors for each triple foam. (The saber needs .057 since the triple foam pods are halved). Each of the waxes work best with a Dema 204C injector with #15 nozzle bushing. You have to unwire the presoak water solenoid. Next you have to add a new 110V 1/2" solenoid to the manifold. Next, cut the QC connectors for each presoak pump on the SDM and Wire one to the old presoak water valve. The other one wires to the new solenoid (in other words, use the old pump outputs to drive each presoak solenoid). By the way color code on wiring is blk 110+, blue 110N, brown ground. Now just run a new hose from the new solenoid and connect at the manifold. Install the injectors just after the solenoids. Oh, also I deleted the fixed pressure pop-off valve and installed a 0-300 psi regulator that would allow me to set the manifold pressure and bypass excess back to the tank. I've done this on a regular vector and its been running problem free since 2010... Note, if your planning on using a powder, use a dual injector. You can can use the second port to get a little more volume than one hose will allow, or you can add a booster or something on the second port, or plug it off. When you set pump speeds: Presoaks about 13, Triple foam about 11, Waxes about 24 worked best for me. Adjust air according to preference.
