Mercury – Transom to Rig Harness | Rigging Accessory | 84-8M0206582

Overview
This harness links the transom gear on a Mercury Racing 450R to the rig center when you’re running a TVM Lite steering setup. It keeps the steering and control signals moving cleanly from the back of the boat to the helm without needing any improvised wiring. The length and layout make it easy to route through the rigging tube or tight corners. Once it’s in place, the system usually feels steadier and more responsive.

Performance & Practical Benefits
With this harness in place, the system isn’t fighting stretched wires or weak connections. The steering actuator gets a steady signal, which you’ll notice when you’re idling around docks or making small corrections. A clean wiring run also cuts down on long-term wear and avoids the patch-job issues that cause random glitches.

Why Buy OEM
OEM harnesses use the right connectors and proper marine-grade wiring, so everything fits the way Mercury intended. They hold up well over time and help you avoid electrical headaches that come from off-brand wiring.

FAQ
Q1: When would I need this harness?
A: Anytime you’re rigging a 450R with a rig center and TVM Lite electric steering.

Q2: Is this a per-actuator harness?
A: No. It’s the main transom-to-rig link, not one-per-actuator.

Q3: Is it okay for saltwater?
A: Yes—just keep the connectors clean during your regular washdowns.

Q4: Anything to check before installing?
A: Make sure the rigging tube is clear and the harness won’t rub on sharp edges.

Q5: What if steering still feels weird afterward?
A: That usually points to calibration or a wiring issue elsewhere, not this harness.
