WD Electronics Side X Side 4-Pin Trailer Adapter
This wiring harness enables your trailer (with a 4-pin trailer connector plug) to have functional brake lights when towed by your SxS if using only this adapter harness or a different brand turn signal kit. When paired with one of our turn signal kits, the harness also allows your trailer’s turn signals to operate. Our trailer adapter is fully compatible with our Turn Signal Kit, providing seamless integration for both brake lights and turn signals on your trailer. The harness includes a dust cap for the 4-pin trailer connector, ensuring durability.
For Rangers, lift your bed and verify you have a 4 pin or an 8 pin connector near the back middle under the tailgate/bed. Choose either the 4-pin or 8-pin selection on this page.
Only compatible with RZR 8-pin connectors. Check on the drivers' side under the bed for an 8-pin connector. If you have a 4 pin connector, this is not compatible. Give us a call.
This trailer adapter only works with trailer with LED taillights. Incandescent bulbs draw too much power causing the lights to work sporadically or not at all.
