13ft Extended Harness for LiMAX Big Box | Clean Dash Routing
Route your LiMAX Big Box display cable to the dash on stretched, 6-passenger, and custom golf carts without cutting or splicing wires.
The 13ft extended harness LiMAX Big Box accessory gives DIY builders and installers the extra reach needed for clean dashboard gauge routing. This Epoch 13ft extension harness is a plug-and-play extension cable for LiMAX Big Box systems, helping you route the golf cart battery meter to the dash on stretched carts, custom carts, and oversized builds while maintaining a clean, factory-looking installation.
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.
Compatibility note

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.
