Control Cable Harness

A tangled bundle of thick, insulated wires forming the refinery's primary control system. The wires are live—glowing with dangerous electrical current—and exposed where the Doctor slices into the harness to reroute power. Some cables spark when cut, and the air carries the acrid tang of overheated circuitry. Romana flinches as he works, the system's unforgiving voltage making every second lethal. The exposed copper ends from frayed insulation hum with residual current under emergency lighting, remnants of the Doctor's effort to sever the refinery's automated countdown.

S16E20 · The Power of Kroll Part 4

Fenner accords final warning to departing crew

The Control Cable Harness forms the refinery’s primary nervous system, its tangled bundle of live, insulated wires sparking and glowing dangerously as the Doctor slices into them. These cables carry the lethal countdown’s pulse; by exposing their innards, the Doctor reroutes their power, turning the system’s own body against itself.

Before: Live and lethal, insulated but exposed where cut earlier; the air reeked with the tang of overheated circuitry

After: Severed and fused by the Doctor’s hands, now inert and cold; their structural integrity broken and current neutralized

S16E20 · The Power of Kroll Part 4

Doctor stops refinery meltdown revealing Krolls true danger

The Doctor slices into the Control Cable Harness while live with a hammer or tool, exposing bare wires that spark and hiss—risky manual reconnection becomes the sole lifeline to halt the countdown, risking electrocution.

Before: Thick insulated bundle crackling with current, exposed at cut ends, coursing through the refinery’s nervous system

After: Partially severed and fused at critical points, sparking has ceased and current rerouted—save for one crucial bridge the Doctor fashions with his hands

S16E20 · The Power of Kroll Part 4

Doctor cuts power to orbital strike

The Control Cable Harness, a live bundle of insulated wires glowing with electrical current, is surgically sliced open by the Doctor to reroute critical power feeds manually. Sparking cables expose raw electrical danger as the Doctor exfiltrates the harness’s purpose to splice the correct ends, halting the launch sequence at the last possible moment.

Before: Intact, live, and functioning as part of the refinery’s main control system, powering the orbital strike mechanism

After: Severed and exposed in places, critical connections fused together, its power feed rerouted to abort the orbital strike
