Linking garmins

I have a 93sv plus on the bow with livescope and was thinking of getting a 93sv uhd for the console. The problem im having is how to link the two to share waypoints. I’ve read about connecting blue and brown wires and different cables so im confused. The only port open on the front unit is a nema 2000 port. Can I just run a nema cable between the units or what? Just want to share waypoints. Thanks

Maybe through the active captain app?

they will link with the built in wifi I believe, I have 2 93sv plus I just installed along with the force tm.
tm and bow unit link auto when turned on, pretty sure the console and bow unit link with the wifi too.
