What it is

The Worcester Bosch Wiring Harness Single Red (87161131530) is a single red wiring harness used within the Worcester Greenstar Heatslave External range of oil-fired condensing boilers. It provides an internal wiring connection between boiler components, carrying the electrical signals and supply required for correct operation.

Signs this part needs replacing

  • Cracked, split or brittle insulation along the harness run
  • Exposed or chafed conductors where the harness passes near sharp edges or hot surfaces
  • Loose, corroded or discoloured connector terminals
  • Intermittent electrical faults or lockouts traced back to the harness or its plugs
  • Localised heat damage or a burnt smell around the wiring

Before you order

  • Confirm the boiler model against the fit list above, as the harness is model-specific
  • Compare the part number marked on the existing harness against 87161131530
  • Check the connector plugs and terminal condition before condemning the harness, as faults often sit at the connection points rather than in the wiring itself
