Clean Power

4-Pin Clean Power T-Harness
IMPORTANT: A T‑harness must not be used in applications with an engine rigging center.
For some applications, the clean power harness connects to the 14‑pin data harness via a T‑harness. The T‑harness can be
inserted at either end of the 14‑pin data harness, according to whether the cranking battery is closer to the engine or the helm.
The T‑harness is optional on systems with a thrust vector module (TVM).
Application
1. All outboard and MerCruiser gas DTS systems
2. Joystick and electric steering systems without a rigging center
3. All triple‑engine and quad‑engine applications

4‑Pin Clean Power Harness with a Single Fuse

Overview
The 4‑pin, single fuse clean power harness has a single 30‑amp fuse at the battery. The harness connects directly to the
engine cranking battery using two ring terminals. A 4‑pin connector at the other end of the harness connects to the engine
rigging center or vessel interface panel (diesel applications).

Application
The 4‑pin, single‑fuse clean power harness is used on applications that use a rigging center and on diesel applications that use
a vessel interface panel (VIP).
