building a new detatched garage.it is board and batten exterior.i ran the wiring for the barn lights above the garge door.well nit thinking the wiring is ran just above the end truss.from where the wire exits the garage wall the is no room to cut for junction box because of truss.plus I already have the board and batten with the hole for the wire so I can't just move it up.my question is can the wire from the light just go into the garge interior and I make the connection in a junction box .? I would then just screw the light bracket directly into the board and batten and into a 2x4 behind the wall the barn light does have a seal on the base.all my wires are 12-2 so a pancake box won't work.im in Tennessee thanks
