The 13ft extended harness LiMAX Big Box accessory gives DIY builders and installers the extra reach needed for clean dashboard gauge routing.

Built for clean custom installations
The Perfect Solution for Stretched & Custom Golf Carts
Built for long carts where standard harness length simply is not enough.
Standard wiring harnesses can come up short when you are building a 6-passenger cart, stretched limo cart, custom UTV, or oversized hunting buggy. This 13-foot golf cart battery harness gives you the extra reach to install your LiMAX Big Box battery system under the seat while still mounting the display where it belongs: cleanly on the dash.
Whether you need extended wiring for a stretched golf cart or simply want to route a golf cart battery meter to the dash without exposed wires, this no-splice golf cart extension harness helps create a cleaner, safer, more professional installation.
13 Feet of Extra Reach
The 13 ft / 3.96 m length provides the slack needed to route the cable from the under-seat battery compartment, along protected frame paths, and up toward the dash on extended builds such as EZGO Express-style or Club Car stretched cart battery upgrades.
Clean, Factory-Look Installation
Instead of draping wires across the floorboard, this extended harness gives you enough length to hide the cable inside factory-style wire paths, secure it with zip ties or clamps, and finish the dashboard area with a clean professional look.
Plug-and-Play Simplicity — No Splicing Required
Protect your communication wiring and avoid unnecessary electrical work.

Installation tips for a cleaner route
Plan the route before plugging in the final connector.
- ✓ Route the harness along protected frame paths and existing wire channels whenever possible.
- ✓ Use zip ties or insulated clamps to prevent sagging, vibration rub, and contact with moving parts.
- ✓ Avoid sharp edges, pinch points, hot components, suspension travel, and tire-spray areas.
- ✓ Leave a small service loop near the dash gauge so the display can be removed later without tugging the harness tight.
- ✓ Do not splice, extend, or daisy-chain communication wiring unless Epoch provides application-specific guidance.
LiMAX Big Box 13ft Extended Harness FAQs
Common questions about fitment, routing, splicing, and custom golf cart installations.
Do I need this 13ft extended harness for a standard 2-seat golf cart?
In most cases, no. The standard wiring harness included with your Epoch LiMAX Big Box kit should provide enough length for standard 2-passenger and many 4-passenger carts. This 13-foot extended harness is specifically designed for stretched, 6-passenger, utility, or custom golf carts where the distance between the battery compartment and dashboard is much longer.
Is this harness compatible with all Epoch LiMAX batteries?
No. This specific Epoch 13ft extension harness is designed for the LiMAX Big Box Series ecosystem. It uses the connector style needed for the Big Box harness/gauge communication layout. Confirm that you have a LiMAX Big Box battery kit before purchasing.
Will I have to cut or splice any wires to install this?
No. The harness is designed as a plug-and-play extension cable. Instead of cutting, soldering, or extending the original wires, connect this 13-foot harness between the LiMAX Big Box battery communication port and the compatible dash gauge/display path, then route the cable cleanly through the cart.
What exactly does this harness connect?
This is a data/communication harness. It is intended to connect the LiMAX Big Box battery BMS / communication side to compatible dashboard gauge or display wiring. It is not a high-current motor power cable, controller cable, or charger-output cable.
Can I connect two harnesses together to make it even longer?
Daisy-chaining multiple harnesses is not recommended. Extra connector joints can introduce moisture risk, signal interference, poor contact, or diagnostic issues. For almost all stretched golf carts, this single 13-foot continuous harness provides enough length for a clean installation.
Is the wiring safe to route under the golf cart?
Yes, when routed correctly. The harness uses a protective outer loom visible in the product images and is intended for golf cart installations. Route it along protected frame paths, secure it with zip ties or clamps, and keep it away from sharp edges, moving suspension parts, hot components, tire spray, and pinch points.
Will this work for EZGO Express or Club Car stretched carts?
This extended harness is commonly useful for stretched or longer carts, including builds like an EZGO Express, Club Car Villager-style cart, or other 6-passenger/custom layouts. Final compatibility depends on the LiMAX Big Box kit, the gauge/display being used, and the wiring path in your specific cart.
What if the connector on my battery or gauge looks different?
Do not force the connectors. Compare your battery-side and display-side connector shapes with the product images before ordering. If your connector differs, contact Epoch support with photos of your battery, dash gauge, and existing harness to confirm the correct part.
