This adapter lets you use John Deere 14-pin attachments with a Caterpillar D-Series skid steer that has a 14-pin machine-side electrical connector. Plug the adapter into your Cat loader, connect your John Deere attachment to the 14-pin output — power up the machine — and you’re ready to run your attachment control functions.
It’s a straightforward plug-and-play solution for operators who want to mix and match attachments and machines from different brands without rewiring harnesses or modifying factory wiring.
The Cat D-Series 14-pin output supports up to six switched electrical circuits when the appropriate factory-installed wiring is present. This adapter is populated to match the standard John Deere 14-pin wiring layout, delivering the control functions your attachment expects.
On the attachment side, the adapter provides the necessary pin-outs to match John Deere’s 14-pin harness specification — including ground, switched outputs, and +12 V power where applicable — so that attachments will function as intended without modification.
This adapter is ideal if you own a Cat D-Series skid steer but want to run a variety of John Deere 14-pin attachments. It allows seamless cross-brand compatibility and simplifies fleet management when you have attachments from different manufacturers.
Before using, make sure your Cat machine actually has the required electrical circuits for the attachment to work; if the loader wasn’t wired with full electrical options, some functions might not be available even with the adapter.
Installation is plug-and-play — no cutting, splicing, or rewiring needed. Simply connect the adapter between the machine and the attachment using the 14-pin connectors. For occasional wiring adjustments or pin-outs, light-duty terminal tools can be used. For regular maintenance, frequent attachment changes, or professional service work, a commercial-duty Deutsch service tool is recommended for durability and ease of use.
A comprehensive user manual is available to assist you with wiring diagrams, pin-out verification, setup instructions, and troubleshooting tips when using machine-to-attachment electrical adapters:

This adapter is assembled with factory-style connector components and wired to standard Cat and John Deere 14-pin harness configurations. However, because electrical systems and attachment wiring can vary — especially in used or aftermarket equipment — we cannot guarantee every function will work in every scenario.
Always verify pin-outs on both the machine and attachment before applying power. If wiring modifications are needed, use the proper tools or consult a qualified technician to ensure safe and correct operation.
This adapter converts a Bobcat-style 14-pin machine-side connector into a John Deere–standard 14-pin attachment connection, allowing you to use John Deere-type attachments on a Bobcat loader or similar machine.
It works for any machine that has a Bobcat-style 14-pin electrical port, and any attachment that uses the John Deere 14-pin wiring standard. Both sides must use the correct 14-pin format for proper compatibility.
No. The adapter is plug-and-play. You simply plug the Bobcat 14-pin connector from your machine into the adapter, then plug in the John Deere 14-pin attachment — no cutting, soldering, or wiring changes required.
The adapter supports the standard 14-pin control wiring: up/down, left/right, and auxiliary circuits — effectively mapping Bobcat’s outputs to the John Deere 14-pin standard so attachment functions should operate normally.
Yes. Installation is as simple as connecting the two 14-pin plugs — machine side to loader, attachment side to tool. No tools or modifications necessary under normal conditions.
Most standard John Deere 14-pin attachments will work, provided their wiring matches the standard 14-pin layout and your Bobcat machine has the necessary control outputs. Proprietary or nonstandard wiring might not be fully compatible.
Yes — the adapter is built with durable 14-pin connectors appropriate for skid steer use. It should tolerate typical job-site conditions such as vibration, moisture, and frequent connect/disconnect cycles.
Yes. As long as the loader has a Bobcat-style 14-pin port and the tool uses a John Deere 14-pin plug, you can move and reuse the adapter across different machines or attachments without modification.
Ensure both 14-pin connectors are fully seated and locked. Confirm the attachment uses a standard John Deere 14-pin wiring layout. If functions are missing, verify that your loader’s control outputs match the attachment’s requirements, and that wiring and connections are intact.
