This adapter lets you run Bobcat attachments (equipped with a 14-pin harness) on a Caterpillar D-Series skid steer loader that has a 14-pin machine-side connector. Simply plug the adapter into your Cat loader, connect your Bobcat attachment to the 14-pin output — power up your machine — and you’re ready to operate.
It’s a straightforward plug-and-play solution for operators who own Cat D-Series loaders but want to use 14-pin Bobcat attachments without rewiring harnesses or altering factory wiring. Perfect for mixed fleets and cross-brand attachment use.
The Cat D-Series 14-pin output delivers up to six switched circuits when factory-ordered with full electrical options. This adapter is populated with the necessary pins for standard accessory control, including: Up/Down, Left/Right, and, where the machine supports it, Right-stick Up/Down.
On the attachment side, the 14-pin Bobcat-style harness is fully supported — including ground and +12 V power on Pin K when required, allowing attachments that rely on a constant power feed to operate correctly.
For machines equipped with high-flow hydraulics or requiring dedicated power output, this adapter ensures the +12 V power pin and required control outputs are passed through. Attachments needing hydraulic flow or power will work as expected, as long as your loader supports those features.
This adapter is ideal for users who:
Always confirm that your loader was ordered with the required electrical control circuits. If your machine lacks those controls, some attachment functions may not be available even when using this adapter.
Installation is plug-and-play — no splicing, no soldering, and no permanent modifications needed. Just connect the adapter between machine and attachment. For occasional wiring adjustments or pin layout changes, basic terminal tools are sufficient. For frequent service or fleet-level use, a professional-grade Deutsch tool is recommended.

This adapter is assembled using OEM-style components and wired to match standard Cat 14-pin and Bobcat 14-pin harness layouts. However, not all machines are shipped with identical electrical control packages, and some attachments — especially used or auction-purchased ones — may have been rewired or modified.
Always verify pin-outs on both the machine and attachment before applying power. If wiring adjustments are needed, use proper Deutsch tools or consult a qualified technician to ensure safe and correct operation.
This adapter lets you use older Bobcat-style 14-pin attachments with a CAT D-Series loader that has a 14-pin machine-side electrical port. It bridges the electrical pinouts so the machine and attachment are compatible.
It works with any CAT D-Series skid steer or loader equipped with a 14-pin output and any attachment that uses the standard Bobcat 14-pin connector. As long as both sides use the correct 14-pin wiring standard, it will plug and play.
No. The adapter is plug-and-play — you simply connect the CAT-side 14-pin plug to your loader and then connect your Bobcat attachment’s 14-pin plug to the adapter. No soldering, cutting or wiring changes are required.
The adapter carries all the standard control circuits from the CAT 14-pin output and maps them to the Bobcat 14-pin configuration. If your loader has the full electrical output package, you can use all standard attachment functions.
Yes — installation is straightforward. Plug the adapter into your CAT loader’s port, then plug in the Bobcat attachment. You’re ready to go, with no additional setup needed.
Most standard Bobcat 14-pin attachments that use conventional wiring should work. However, if an attachment uses advanced or proprietary wiring beyond the standard 14-pin layout, functionality may be limited depending on your machine’s control package.
Yes. The adapter uses heavy-duty 14-pin connectors designed for harsh working environments, including vibration, moisture, dust, and frequent attachment changes — ideal for skid steer work sites.
Yes. As long as the loader has a CAT D-Series 14-pin port and the attachment uses a Bobcat 14-pin plug, you can disconnect and reuse the adapter across machines or attachments without any changes.
Confirm that both 14-pin connectors are fully seated and locked, ensure the attachment uses a standard Bobcat 14-pin wiring, and verify that your CAT loader has the necessary control outputs. Issues are usually caused by connector misalignment or mismatched wiring standards.
