Place the in-line "T" as far back as possible away from the instruments.
This will add some pneumatic resistance between the instruments, preventing
cross-talk. Placing the "T" under the seat-pan is usually far back enough.

Assuming the red line is from the TE, you should connect it to the TE
input
on the LNAV. You should also connect an in-line T and use the red TE for
the
other vario if you have one. If the additional vario is mechanical, it'll
have two inputs, the other goes to the flask.

all the best,
