What it is

A 9-way wiring harness manufactured by Worcester Bosch for use in the Greenstar Heatslave External oil boiler range. It provides the multi-pin wiring connection between the boiler's electrical components and the control assembly, carrying low-voltage signals and supply to the relevant plug-in points.

Signs this part needs replacing

  • Boiler fails to fire or locks out with no fault indicated by the control
  • Intermittent electrical faults that change when the wiring loom is moved or disturbed
  • Cracked, brittle or heat-damaged connector housings or insulation
  • Corrosion, burning or discolouration at the harness terminals
  • Faulty or loose plug connections at the harness ends

Before you order

  • Confirm the appliance model is one of the Greenstar Heatslave External variants listed above
  • Check the existing harness for the 9-way connector pattern and pin count
  • Verify the Worcester Bosch part number 87161136180 against the old component
  • Isolate the boiler electrically before inspection or replacement
