Unlock the full value of your older 14-pin Bobcat attachments by running them on your newer Caterpillar D-Series skid steer loader using this plug-and-play electrical adapter. Simply connect one end to your Cat D-Series machine and the other to your legacy Bobcat 14-pin attachment, power up the loader, and you are ready to work. It’s a clean, simple solution for owners who want to mix brands without rewiring harnesses or modifying expensive attachments.
This adapter is purpose-built as a Bobcat 14-pin to Cat D-Series 14-pin skid steer adapter, giving you a reliable way to run common hydraulic attachments such as snow blowers, brooms, rakes, and more while keeping your controls intuitive and loader-cab friendly.
Important – 7-Pin Attachments Not Supported: This adapter will not operate modern Bobcat 7-pin CAN-controlled attachments. Those tools require a dedicated bypass harness or controller. To match the correct harness for your specific machine and attachment combination, please use our selector guide:
Cat D-Series 14-Pin Output: When properly optioned, the Cat 14-pin system can provide up to 6 switched electrical functions. It is the owner’s responsibility to verify that the machine was ordered with the necessary electrical controls and buttons installed in the cab. This adapter is wired with 8 active pins, supporting Up/Down, Left/Right, right-stick Up/Down, Ground, and +12 V power so you can drive typical 14-pin Bobcat attachments from the Cat joystick controls.
On 2025 and newer Cat 255/265 models, this adapter also incorporates the K to P pin connection for dedicated switched power. A hidden jumper is stored inside the female connector with shrink tubing over the pin. If you need to activate High Flow hydraulics, simply remove the shrink tubing and insert the jumper into pin K or N as required by your machine to signal High Flow. This preserves Cat’s factory logic while giving your attachment the power it needs.
This adapter is engineered to use the OEM-style electrical interface from your Caterpillar D-Series machine and map it correctly to older Bobcat 14-pin attachments. The loader you connect to must still have enough factory control buttons installed to operate all of the attachment’s functions you intend to use.
If you expect to move or re-pin connectors frequently on your attachments, keep in mind that we include single-use pin tools with the kit. For shops, fleets, or heavy users who want something more robust and reusable, we strongly recommend upgrading to our commercial-duty Deutsch tools below.
Both ends of this product are built to factory pin specifications with original factory parts. We cannot guarantee that your machine was ordered with all of the factory controls, nor can we guarantee that your attachment is pinned accordingly as well. This is especially evident with auction attachments or second hand items bought on the internet. We include tools and instructions on moving pins to make everything align.
This adapter lets you run older 14-pin Bobcat attachments on a newer Caterpillar D-Series skid steer equipped with a 14-pin control plug. One end connects to the Cat D-Series machine, and the other end connects to the 14-pin Bobcat-style attachment so you can operate it from your factory joystick buttons.
No. This adapter is only for older 14-pin Bobcat attachments. Modern Bobcat attachments that use the 7-pin CAN system require a separate bypass harness. Use the Skid Steer Genius selector guide to choose the correct 7-pin harness for your attachment before ordering.
This adapter is designed for Caterpillar D-Series skid steer loaders, and other Cat machines that are factory equipped or retrofitted with a 14-pin electrical connector and joystick controls. As long as your Cat D-Series has the 14-pin plug and the auxiliary buttons installed, you can use this adapter with 14-pin Bobcat-style attachments.
Cat 14-pin can provide up to six switched outputs if your machine was ordered with the full control package. This adapter is wired with eight pins: Up/Down, Left/Right, Right Stick Up/Down, ground and +12V power. That gives you plenty of control for most 14-pin Bobcat attachments, provided your machine has enough active buttons installed to drive those functions.
On 2025 adapters, a K-to-P jumper is included for newer Cat 255/265 machines. The internal jumper links the power on Pin K to Pin P to provide a dedicated switched power signal that your machine uses to enable high-flow hydraulics. There is a hidden, shrink-tubed jumper inside the connector—simply remove the shrink tubing and place the jumper into Pin K or N as instructed to turn on high-flow when needed.
Most factory-wired attachments plug in and work without repinning. However, auction, second-hand or previously modified attachments may not follow original pinouts. If you need to move pins, Skid Steer Genius provides free single-use pin tools with many kits, and you can also purchase a commercial-duty Deutsch/HD pin tool for frequent repinning using the links in the product description.
No. The adapter simply routes electrical control signals from your Cat 14-pin plug to the 14-pin Bobcat-style attachment. It does not alter hydraulic flow or pressure. As long as your machine and attachment are matched correctly and in good condition, using this adapter will not negatively affect your hydraulics or electronics.
