🔧 Product Description

⚙️ Key Features

• 2.858 kg
• Full made-up assembly rather than a branch lead
• No published engine applications, so order by part number

🔌 Function

Carries the supply and signal circuits between units as one pre-made assembly, with the connectors, lengths and branches already set so each circuit lands where it should.

⚠️ Common Signs of Failure

• Intermittent faults that come and go with movement or vibration
• Warning lamps and stored faults across several unrelated circuits
• Insulation chafed, melted or split where the harness passes a bracket
• Green or white corrosion inside a connector, or a connector full of water
• Pins pushed back, bent or burnt in a connector body

🛠️ Service Notes

• Photograph the existing routing and clipping before removing the old harness
• Keep the harness clear of hot and moving parts and support it at the original clip points
• Check earth points and connector seals while the harness is out, as most harness faults are corrosion at a joint rather than a broken wire

📦 Condition
