Mercury – Engine to Vessel Interface Panel Extension Harness 10 Foot | Sterndrive Harness Extension | 84-879312T01

The Mercury Engine-to-Vessel Interface Panel (VIP) Extension Harness is designed for diesel sterndrive installations where the vessel interface panel is mounted farther from the engine. It provides a factory-correct extension between the engine and VIP without modifying, cutting, or stressing the original harness.

The 10-foot length allows relaxed, clean routing through larger engine rooms and flexible mounting layouts. It helps maintain stable communication between the engine and interface panel while keeping wiring organized and free from tight bends or unnecessary strain.

FAQs

1) What does this harness connect?
It extends the connection between the diesel engine and the vessel interface panel (VIP).

2) Is this harness for DTS systems?
No. This extension harness is designed for non-DTS diesel sterndrive applications only.

3) Why use an extension harness instead of splicing?
Using an OEM extension preserves signal integrity, prevents communication errors, and maintains factory wiring standards.

4) When is a 10-foot harness needed?
It is commonly used when the VIP is mounted farther from the engine in larger engine rooms or flexible helm layouts.

5) Does this replace the original harness?
No. It extends the existing harness without replacing or altering factory wiring.
