Rodent Tape for Engine Wiring Harness, 19 mm × 20 m — Genuine Honda 4019-2317

Genuine Honda OEM part 4019-2317 — a rat-proof vinyl harness tape made by Teraoka (manufacturer reference 347G). Wrapped over engine wiring it puts a physical layer between the wire insulation and rodent teeth. One roll is 19 mm × 20 m (about 65 ft).

Specifications

Honda and the part number 4019-2317 are used here to identify the part this tape is specified against.

Teraoka and 347G are the manufacturer's reference and remain the property of their respective owner.

How it works

The adhesive layer carries microcapsules of capsicum (chili pepper) extract — the same compound that makes a chili hot, and a food additive rather than a poison. Rodents dislike the taste, stop chewing and do not come back to the same spot. The tape repels; it does not kill or injure.

Where it is used

• Engine and body wiring harnesses, sensor leads and connector tails
• Harness runs passing through wheel wells, fender gaps and firewall grommets
• Fuel, brake and vacuum lines in areas with known rodent activity
• Stored vehicles, boats and equipment where harness damage happens between seasons

How to apply it

1. Wipe dust, oil and moisture off the surface — adhesion fails on a dirty harness.
2. Start about 2 in before the section you want to protect and finish about 2 in past it.
3. Wrap with roughly 50% overlap, pressing firmly as you go.
4. In areas exposed to sunlight or rain, apply a second layer — the manufacturer notes the repellent effect shortens with UV and water exposure.

Handling and safety

• Wash hands after handling — the capsicum can irritate eyes and mucous membranes.
• Sensitive skin: wear gloves, or wash hands frequently.
• Do not put the tape in your mouth or lick it.
• Keep out of reach of children.
• Not for application to the human body.

Questions

What is Honda 4019-2317 used for?

It is the OEM rodent-deterrent tape wrapped around engine wiring harnesses on Honda vehicles. It repels rodents mechanically and by taste, protecting the wire insulation underneath.

Does this tape kill mice or rats?

No. The capsicum extract repels them; it does not kill or injure. Pest control is a separate job — this protects the harness.

Is this the same as Teraoka 347G?

Yes — 347G is the manufacturer's reference for the tape supplied as Honda part 4019-2317: PVC film, rubber adhesive, gray with the printed rat pattern, 19 mm × 20 m, 0.2 mm thick.

How many rolls do I need?

One roll covers about 20 m of harness at 50% overlap, so roughly 10 m of finished run — less if you double-layer exposed sections. Most engine-bay jobs take two to three rolls.

Will it hold up in an engine bay?

The PVC backing and rubber adhesive are made for underhood conditions, but the repellent effect fades with prolonged sunlight and water exposure. Double-layer any run that sees weather.

How is this different from peppermint oil sprays?

Sprays are topical and wash or evaporate away. This is a wrapped physical barrier that stays on the harness, so protection does not depend on reapplication.

Will this fit my vehicle's harness?

The roll itself wraps any harness you can reach, but 4019-2317 is the part number Honda specifies for its own vehicles. The models and years that call for it are listed in the Honda 4019-2317 fitment cross-reference; for anything else, measure the run you need to cover and wrap that.

Can I wrap it over wiring that has already been chewed?

It protects insulation that is still intact. If copper is already exposed, repair or replace that section of wire first - tape over a bare conductor is not a repair.

Is it the OEM width and thickness?

Yes: 19 mm wide, 20 m long and 0.2 mm total thickness, the dimensions the harness tape is specified at, so it wraps and conforms like the original.

Rodent tape, rat tape, mouse-repellent harness wrap: the same part

This roll gets searched for under several names — rodent tape, rat tape, mouse repellent tape for cars, anti-rodent harness wrap. They all describe the same object: a capsaicin-treated PVC tape wrapped over a wiring harness so rodents stop chewing at the insulation underneath. It is not a spray, it does not kill anything, and the deterrent sits in the adhesive layer under the backing rather than on the surface, so it does not wipe off.

What it is wrapped around

The harness rodents reach is the one running from the engine bay into the cabin — over the cam cover, along the firewall, into the injector loom. Which models and years call for this part is listed in the Honda 4019-2317 fitment cross-reference.
