classicretrofit Posted January 20, 2024 Posted January 20, 2024 Push Button Placement We supply a single push button switch with led ring illumination. The switch is a momentary push button and the LED is used to indicate A/C status. The switch and harness is pre-wired. Some 911s have a blanked off switch hole on the dashboard near the wiper/light stalks. If you use this hole it will need careful opening of both the front vinyl AND the metal work behind. The suggested approach is to enlarge a little very carefully with a stepped metal cutter, then finish by hand with a round file. Carefully does it! Discrete control button placed in blank to the right of heater sliders. The ring led indicates A/C status. You might have a centre console with original A/C controls. Because our system does not have a separate fan and the temperature is climatically controlled, these controls no longer make sense. Leaving them there causes no harm, or you could blank off that panel and add our control button there. Control button cable routing Please note that if the control button is already attached to the cable, it must be secured to the facia panel first. Pass the cable through the front of the facia panel. Also pass the cable through the securing nut and washer, then fasten the button. If you fail to do this, you won’t be able to mount the button without desoldering all the connections! On the bulkhead (behind the radio) there are a couple of factory plastic grommets. You can remove one of these to route the control cable though to the luggage bay. This is easier when the old fresh air blower has been taken out. Use a rubber grommet on any through holes for the wiring.
classicretrofit Posted January 21, 2024 Author Posted January 21, 2024 For those using our half kit, you do not have to install our cabin button. You can use the factory blower switch to turn on the AC. This requires wiring the orange wire in our loom to the red/white wire on the factory blower 4 pin connector. Installation of the half kit requires changing settings in the ECU. Please see our Setup and Test Guide.
