hey, i installed the ac delete heater box and i have a 91 with the vacuum controlled vents. my question is where do the vac uum lines go to that are in the factory wiring harness for the heating/ac.? also i connected only the yellow, orange, blue, and green wires because that is what only was on the wiring that came with the heater box. was i correct by cutting the old harness and connecting them together with te new heater box harness? what should i do with all the other wires? i dont need them crrect?
