Upon delivery, the DanVard harness arrives in a sturdy, well-padded cardboard box designed to protect the delicate connectors during shipping. Inside, the single, complete engine wiring harness is coiled neatly and secured with zip-ties. The harness itself is wrapped in OEM-style convoluted tubing and fabric loom in key areas, mirroring the factory appearance and protection. Each connector is either bagged or has protective caps in place to prevent dirt or damage to the electrical pins—a sign of thoughtful packaging. It’s important to note that no additional hardware, wiring diagrams, or installation tools are included. The product assumes you are replacing an existing harness and will use the original mounting brackets, clips, and bolts. The build quality upon first inspection feels robust; the wires have a good heft to them, and the connectors are crisp and new, with no visible mold flash or defects. This positive first impression is a key part of the 68081220AI pros and cons analysis, as quality out of the box is a reliable indicator of longevity.

Begin by disconnecting the negative battery terminal to prevent any short circuits or electrical damage. Gather your tools: a basic socket set, trim panel tools, a marker, and masking tape or a label maker. It is highly advisable to have the factory service manual or a reliable online resource for your specific JK year for torque specs and hidden fastener locations. Take your time to study the routing of the old harness before removing anything.
Methodically disconnect every electrical connector on the old engine harness. We recommend taking photos with your phone from multiple angles before disconnecting each major section. Use your marker or labels to identify any connectors that are not intuitively obvious, though the DanVard harness’s accurate labeling will help immensely here. Carefully remove the harness from its plastic retainers and mounting brackets, noting their positions. Gently pull the harness through the firewall grommet.
Lay the new DanVard 68081220AI harness next to the old one. Compare them length-for-length, branch-for-branch. This verification step is crucial to ensure you have the correct part and builds confidence. Transfer any necessary mounting brackets or clips from the old harness to the new one. This direct comparison often answers the question “should I buy 68081220AI harness?” because you can see the quality difference firsthand.
Route the new harness through the engine bay, following the exact path of the original. Start by feeding the main firewall grommet through first. Click the harness into all its plastic retainers and secure it with the original brackets and bolts. Do not force anything; if a connector isn’t aligning, check for incorrect routing. Begin connecting electrical connectors, using your photos and labels as a guide. The connectors should click firmly into place without excessive force. This harness is designed for this precise fit.
Once all connectors are attached and the harness is fully secured, double-check that no wires are pinched or hanging near hot or moving parts. Reconnect the negative battery terminal. Turn the ignition to the “ON” position (without starting the engine) and scan for any check engine lights that may appear immediately. Listen for the fuel pump priming. If all seems well, start the engine. Let it idle and monitor for smooth operation.
After a successful idle, use an OBD2 scanner to check for and clear any latent codes. Take the vehicle for a gentle test drive, paying attention to throttle response, idle stability, and instrument cluster warnings. Ensure all accessories powered by the engine harness (like fans) operate correctly. For long-term care, periodically inspect the harness for any signs of chafing or loose connectors, especially after off-road use. Our Jeep JK maintenance guide has more tips.

We installed the DanVard 68081220AI harness on a 2013 Jeep Wrangler JK Unlimited with a 3.6L engine that had intermittent misfire codes (P0300) and erratic sensor readings traced to a failing OEM harness. The installation was performed in a home garage setting to simulate the typical DIY experience. After installation, we monitored the vehicle over four weeks and approximately 1,200 miles of mixed driving, including highway commutes, city traffic, and light off-road trails.
The primary performance metric for a wiring harness is flawless electrical communication. Immediately after installation, all pending misfire codes cleared and did not return. Sensor data, viewed via a live OBD2 scanner, showed stable readings for oxygen sensors, coolant temperature, and crankshaft/camshaft position. Throttle response felt crisp and immediate, resolving a slight hesitation that was present before. Most importantly, the electrical system’s reliability was perfect—no flickering lights, no random codes, and no starting issues, even after the vehicle sat for several days.
In daily driving, the harness performed invisibly, which is exactly what you want. During a longer highway trip, constant cruise control operation and sustained high engine loads presented no issues. The true test came during a weekend trail ride with higher engine temperatures and significant vibration. The harness maintained integrity, with no new fault codes appearing. The connectors remained securely seated despite the jostling, a key consideration for any Jeep owner.
DanVard claims high-temperature resistance and OEM-compatible fitment. Our testing confirmed these claims. The harness showed no signs of softening or odor near the exhaust manifolds, a common hot spot. The fitment was indeed precise, making the installation process more about patience than modification. The promise of a “durable and reliable” harness held true throughout our testing period. This hands-on validation is critical when deciding if the DanVard 68081220AI is worth buying over other options.
When considering a replacement harness, you’ll typically encounter three options: a new Mopar (OEM) harness, a remanufactured/used harness, or a new aftermarket harness like this one from DanVard.
| Feature | DanVard 68081220AI | New Mopar OEM | Remanufactured/Used |
|---|---|---|---|
| Price | $$$ (Significant Savings) | $$$$ (Most Expensive) | $ (Least Expensive) |
| Quality & Materials | New, high-quality wires & connectors | Guaranteed OEM specification | Uncertain; may have old, brittle wires |
| Warranty | 1-Year Limited | Factory Warranty | Often 90 days or less |
| Reliability | High (Based on our test) | High | Variable/Potentially Low |
| Fitment | Precise Plug-and-Play | Perfect | Good, but connectors may be worn |
Choose the DanVard harness if you want a balance of cost and guaranteed new-part reliability. It’s ideal for the capable DIYer or a shop looking for a trustworthy part that won’t come back with issues. It represents the best value when you need a long-term fix.
Consider a new Mopar harness only if money is no object and you require absolute factory provenance, perhaps for a concours restoration. A used harness might be a temporary gamble for a vehicle you plan to sell quickly, but it risks immediate failure. For a detailed comparison of other aftermarket brands, see our engine harness brand showdown.
Use a quality OBD2 scanner to monitor live data and perform a visual inspection of your current harness for cracked insulation, burnt spots, or chewed wires. Confirm the problem is harness-related to ensure the buy DanVard 68081220AI wiring harness decision is the correct one.
Your phone is your best friend. Take dozens of clear, well-lit photos from multiple angles before disconnecting anything. This visual reference is more valuable than any generic diagram.
A set of trim removal tools and a good flashlight/magnetic parts tray will make the job infinitely smoother and prevent broken clips and lost bolts.
Don’t try to rush. Break the job into stages: battery disconnect, intake removal (if needed), connector labeling, harness removal, comparison, installation. This prevents overwhelm and mistakes.
After all connectors are plugged in but before final routing, gently tug on each connector to ensure it’s fully latched. A loose connector is a common post-installation issue.
After installation, use your scanner to clear all adaptive memory and pending codes. Let the vehicle idle with all accessories off for 10-15 minutes to allow the ECU to relearn base parameters.
The DanVard 68081220AI wiring harness has a current market price of approximately $1429. While this is a substantial sum, it must be compared to the OEM alternative, which can cost $2,500 or more from a dealership. When you analyze the DanVard 68081220AI worth buying equation, the value becomes clear: you’re getting a new, high-quality part that solves a critical problem for about 40-50% less than the factory part. We have not found consistent discounts or bundles for this item, as it’s a specialized component.

Absolutely, provided you have confirmed your factory harness is faulty. When you compare the cost of a new Mopar harness, the diagnostic time at a shop, and the value of having a reliable vehicle, the DanVard unit offers exceptional value. It’s a permanent fix with new-part reliability for significantly less money, making the initial investment well worth it to solve a major problem.

Yes, absolutely. The harness is designed to be installed with the engine in place. The job involves removing the intake manifold and other components for access, but a full engine removal is not required. This is a standard in-vehicle repair procedure.
This harness is specifically engineered for the 3.6L Pentastar V6 in the 2012-2015 JK Wrangler. It will not work with the older 3.8L, the diesel, or the newer 2.0L/3.6L in JL models. Always triple-check your factory part number and vehicle specifications before purchasing.
