Ensuring Safe and Reliable Rack-to-Vehicle Connection

Safe overfill prevention connections. It’s top of mind, we know. And efficiency. You need to know which cable goes with which plug and you want the correct information you need quickly. This page has all the elements that with help you make the right decision for your equipment.

If you’re reading this, you probably need a replacement cable, since your system originally came fully equipped. You may know your part number, so are ready to send us your P.O. Perhaps your part number has worn off and you are using our cable guides to find the correct replacement cable; once you establish what it is, you can also send in the P.O. to us. Or, you might give our customer service reps and service technicians a call so we can walk you through the information we need to find the right cable for you. 

Identifying the cables by color (blue or green) and configuration (2-wire or 5-wire interfaces) is vital for proper selection. As an example: 2-wire probes use the green socket. Duoceptâ outputs give you the capability to use either socket; the truck electronics allows both outputs. Any specialties may require further questions to qualify your cable needs. We start with the basic identifying characteristics, then pick the proper cable from there. 

Asking the Right 3 Questions   

Whether you look up the information yourself or have us help you find your replacement cables, there is a series of questions that will easily cull the choices down. You’ll need to answer these three questions:   

  1. What color is your existing plug?
  2. How many pins are there for j-slots?
  3. Do you need a straight or coiled cable? 

These three questions generally provide the information needed to select your replacement cables. Additional consideration may apply, depending on whether or not it needs to be wired directly to the terminal strip via a junction box or if the other plug connection is at the end of the rack. What is asked in this instance is: 

  • Is it hard wired or a pull away cable? 

Most often, we field these questions for people looking for replacement cables at the terminal. If you are trying to address a truck set-up, then we ask the questions in the opposite vein. For example: what kind of cables are at the rack? 

Whether you use these questions to guide yourself through our cable guides or call us for help, these will help cull the choices quickly. Sometime people wonder why we ask these questions—after all, they bought the cable from us, so we should know! And we do—we just need to narrow down the options. Did you know that your location can even provide information? The 5-wire blue cable is largely, though not exclusively, used west of the Rockies. Scully Customer Service Representative Glenn McKay says, “While we do have a very large number of cables, choosing the right replacement cable is a fairly simple process. Customers may have 20 questions about them, but it only takes about three or four—and a minute or two—to find what you need.”
