Honda part 4019-2317 is a rodent-deterrent harness tape, not a vehicle-specific part in the usual sense. This page explains what the number identifies, how to confirm whether your vehicle uses it, and what the tape physically is — so you can buy the right roll without guessing.
What the part number identifies
4019-2317 is a Honda service part number. In Honda's parts system the number identifies the tape itself — a 19 mm × 20 m roll of gray PVC harness tape with a printed rat pattern — rather than a bracket or a component that differs by model year. It appears in Honda parts diagrams on the harness runs that need rodent protection, typically the engine harness, sensor leads and runs passing through grommets.
How to confirm your vehicle uses it
- Look at the harness you want to protect. If the existing wrap is gray with a faint rat print, that is this tape.
- In a Honda parts diagram, find your harness section; 4019-2317 appears as a listed tape item where the diagram calls for rodent-deterrent wrap.
- If your harness is wrapped in plain black cloth or vinyl tape, you can still fit 4019-2317 — it is a wrap, not a connector-dependent part.
Fitment is therefore about the harness, not the model year. Two vehicles with the same engine harness take the same roll.

How much tape a job takes
At the recommended 50% overlap, one 20 m roll covers roughly 10 m of finished harness. Add for double-layering any run exposed to sunlight or rain. A typical engine-bay job takes two to three rolls; a full harness rebuild takes more.
What it does and does not do
The adhesive carries microcapsules of capsicum (chili pepper) extract. Rodents dislike the taste and stop chewing, so the tape repels rather than kills. It protects the wire insulation underneath; it is not a pest-control product and does not reduce a rodent population.
Handling
Wash hands after handling — capsicum can irritate eyes and mucous membranes. Sensitive skin should wear gloves. Do not put the tape in your mouth. Keep out of reach of children.
Fitment: what Honda's own catalog actually says
Two US Honda dealer catalogs were checked on 28 October 2026. One lists 4019-2317 with the explicit note "No application/vehicle fitment information available for this product"; the other describes it as a wrap for "any trouble spots" rather than as a part that fits named models and years. That matches what the part is — a service accessory sold as a roll of tape, not a component keyed to a model year.

Third-party listings that print a model-year range for this part number are aggregating catalog metadata, not quoting Honda; the ranges disagree with each other. Treat any model list you see as indicative and confirm against your own harness, using the three checks above.
Where the wrap goes on a vehicle
The tape is applied to harness sections, so the useful unit is the run, not the vehicle:
| Run | Why it is exposed | Typical length |
|---|---|---|
| Engine harness over the cam cover | Warm, accessible, soy-based wire insulation | 1–2 m |
| Firewall pass-through and grommet runs | Rodents follow the same openings the harness uses | 0.5–1 m |
| Injector and sensor leads | Short branches, hard to inspect, expensive to replace | 0.3–1 m |
| Underbody and wheel-arch runs | Open access from below, splashed clean of deterrents | 2–4 m |
| Cabin entry loom behind the dash | Entry point after rodents come through the firewall | 1–2 m |
Rolls needed for a given run
At the half-wrap overlap Honda recommends, tape consumed is roughly twice the finished run length. One 20 m roll therefore yields about 10 m of wrapped harness. The roll we stock is 19 mm × 20 m, Honda part 4019-2317.
| Finished run | Tape consumed | Rolls |
|---|---|---|
| 3 m | 6 m | 1 |
| 6 m | 12 m | 1 |
| 10 m | 20 m | 1 |
| 15 m | 30 m | 2 |
| 20 m | 40 m | 2 |
Safety and compliance
Capsicum is an irritant, not a poison. Wash hands after handling; avoid touching eyes, nose or mouth; wear gloves if your skin is sensitive. Keep away from children and do not put the tape in your mouth.
American Honda's US parts listing for this part number carries a California Proposition 65 notice: Cancer and Reproductive Harm — www.P65Warnings.ca.gov. If you resell this part into California, that warning travels with the product. The safety data sheet published alongside the Honda parts listing is the reference document for handling and disposal.
Where to go next
This page answers one question — what 4019-2317 is and whether your harness takes it. The rest of the site covers the buying and the alternatives:
- Honda 4019-2317 rodent tape, 19 mm × 20 m — the roll described above, with the full spec table, roll price and stock.
- Electrical tape selection matrix — thickness, UL temperature class, breakdown voltage, peel adhesion and tensile strength for every tape we stock, measured and side by side.
- Automotive rodent and harness protection — the range this tape belongs to.
- Wire harness cloth tape — acetate cloth tape for the friction layer under a harness wrap, if you are rebuilding the loom rather than patching a run.

If your vehicle uses 4019-2317, the wrap only protects what it covers — the rodent tape guide shows which harness runs to tape, how many rolls a job takes, and how the tape compares with sprays, split loom and electronic repellents. Packs are on the product page.
