Four "power" wires terminate under passenger seat/bench, straight to the fuse box. Use any available/empty spaces that correspond to existing supply rail (terminal 30 --> permanent 12V).
Remaining 3 wires need to be brought to the BCM(plug B and C).
Remove door step and run them under the floor lining from the driver seat to the A pillar.
Access to the BCM plugs on a T6.1 is very limited. Accessing from the bottom of the dash get them unplugged and next remove Instrument Cluster. Then accessing via IC opening pull the wiring looms(plugs B and C) to the top. Not so easy but doable. After that open up the plugs and click in your 3 preterminated wires. Reassemble everything together and complete coding.
