Bought the house last year. One branch was disconnected at the main trunk, I want to re-connect it, yet it is level with the a/c coil. Should I use existing cut out that was blocked off, or should I cut into the trunk above the coil? This branch was probably taken out of service when the a/c was installed by the previous owners.

Above the coil or somewhere else in the trunkline

Thanks for the response.
