21395663 Wiring Harness | Genuine Volvo Penta Part

🔧 Product Description

Transmission-side electrical harness used in specified Volvo Penta IPS EVC-D and EVC-E installations. It links the IPS drive/transmission electronics into the Electronic Vessel Control network with the correct OEM connectors, shielding, branch routing and marine-grade protective covering.

⚙️ Key Features

• Genuine Volvo Penta IPS transmission wiring harness
• Designed for EVC-D and EVC-E propulsion networks
• OEM sealed connectors and marine protective sleeving
• Carries transmission/drive power, control and communication circuits
• Selection controlled by IPS package, EVC generation and installation layout
• Engine type: Volvo Penta IPS marine propulsion with electronic transmission and steering control

🔌 Function

Connects the IPS transmission/drive electronics to the vessel EVC network so shift commands, drive status, alarms and control-unit communications can be transmitted reliably.

⚠️ Common Signs of Failure

• Intermittent gear engagement or loss of shift command
• EVC communication, transmission or drive fault codes
• Corrosion, water ingress or damaged seals at connectors
• Harness chafing, crushed sections or broken conductors

🛠️ Service Notes

• Compare the new harness with the old one before fitting — check the connector types, the number of pins and the branch lengths, and lay it out alongside the old loom to confirm every branch reaches its component
• Disconnect the batteries before unplugging or fitting a harness, and support the loom as you work so its weight never hangs on a connector or a bulkhead grommet
• Route it along the original path and secure it with the original clips and ties, clear of hot exhaust surfaces, sharp edges and anything that moves; leave a service loop at each connector rather than pulling a branch tight
• Push every connector home until the lock latches and protect the joints with a marine dielectric grease — an intermittent electrical fault is far more often a partly seated or salt-corroded pin than a broken wire
• Renewing the harness is the right repair where insulation is chafed, brittle or oil-soaked, or where corrosion has tracked inside the connector bodies; patch repairs in a damp engine bay tend to fail again, and any single conductor that is repaired should be joined with tinned marine cable of the same gauge, a proper crimp and adhesive-lined heat-shrink
