The heater relay may not be in place, however most companies run wires for options even if they don't install them. They just leave other bits out. In your case you don't have the heater or the relay, but the red power wire may still be installed. You just plug in the relay and now you would have power and ground up through the clock spring so that you could power the heaters you want to add. You need to get power through the clock spring, or you cannot connect the heater and the other power sources are not ones you want to use as they cannot carry the extra load. To get to the wiring you need to pull the steering wheel trim pad and get to the back of the connector you took a picture of. That power would be at pin 2 in the 14-pin connector. See the above post with the heated wheel circuit.
If you add the relay and test with a test light attached to ground to probe that wire, it should show power when the key is turned on. Then you could connect the red heater wire there and the black through the switch to the brown ground wire at pin 12 in that same connector. The relay is in the under-hood fuse box on the left of the engine bay.
With it plugged in, you should also feel it click on when you have someone turn the key on.
Then unplug the white connector you took a picture of, then see if you have the switched power at pin 2. Then you may need to add the contact into the white connector to get that power. Not a hard thing but you need the connector.
