Marrying cameras in Premiere Pro

I’m editing a video in Premiere, Camera 2 actually has better audio. When I marry Camera 1 and 2 and sync them to audio even if I select track 2 it syncs to Camera 1 audio. Anyone know of a work around. I’m a novice. This is what I followed Multi-Camera Editing in Adobe Premiere Pro CC tutorial - YouTube

Edit lounge was always a good resource for me

I got someone else to take over. Thanks, for sharing I’ll take a look.
