Here is the complete BCM pinout for FL Caddy. You should be able to find what you looking for

Activation in VCDS can be tricky for many different things. I actually came across few weird ones myself, for example when fitting interior monitoring I had to select the switch being in drivers door, not the pillar as it is as it wouldnt work otherwise...even when pillar option was also there
Remember to save the VCDS scan for the module you will be working on before you change anything too
