Rak 19026 + Sensors

I am looking to build a mailbox sensor and an array of motion sensors in my woods. This week I picked up a RAK 19026 to build the mailbox sensor. Without knowing which way I wanted to go I got the 1903 light sensor and 12015 vibration sensor. When I went to Detection Sensors it looks for which GPIO pin to use and I am not sure where the mapping is or how to calculate or identify it. I checked out the RAK mapping calculator but the 19026 isn’t listed. I tried a number of combinations and just lost track after hours of rebooting and setting the GPIO number. Any help would be greatly appreciated. Lastly, I did find RAK WisBlock Sensors - firmware support? but none of the sensors I’m using were listed.
Thanks all.
