H2: Frequently Asked Questions About Trailer Electrical Cords

1. What is the difference between Green and Black 7-way trailer cords?

The color indicates the wire gauge configuration.

  • Green Cords (ABS): Designed specifically for Anti-Lock Braking Systems. They typically feature a heavier gauge wire configuration (1/8, 2/10, 4/12) to handle the higher power demands of the ABS module.

  • Black Cords (Standard): Standard lighting cables used for non-ABS trailers or older equipment. Victory Technology recommends Green ABS cords for all modern semi-trucks.

2. Are your trailer plugs compatible with all trucks?

Yes. Our heavy-duty 7-way plugs and sockets are manufactured to the SAE J560 standard, making them universally compatible with Freightliner, Kenworth, Peterbilt, Volvo, and other major North American truck brands.

3. Do your electrical coils resist cold weather?

Absolutely. Similar to our air lines, our electrical cords feature “Arctic Grade” jackets. They remain flexible and resist cracking in temperatures as low as -40°C (-40°F), ensuring your electrical connection stays secure even in winter.

According to SAE standards:

  • White: Ground
