CADUFUELLY Deutsch DT 2-in-1 Y Adapter Harness — Dual DT Splitter, 19.6" IP68, 300W

CADUFUELLY 2-in-1 Deutsch Dual DT adapter is a plug-and-play Y-shaped wiring harness that converts a single DT connector into two Deutsch DT outputs for powering fog lights, work lights, chandeliers and other 12V lighting accessories.

This compact dual-split harness simplifies adding or upgrading auxiliary lighting without cutting factory wiring. Built from ABS, durable plastic and copper conductors, the CADUFUELLY adapter follows original-equipment specifications so you can swap it in without modifying connectors. It supports heavy-duty 12V systems up to 300W, is IP68-rated for harsh environments, and comes as two 19.6-inch harnesses—ideal for off-road, marine, construction, or custom lighting projects.

How does this adapter make installing extra lights easier?

Instead of splicing into vehicle loom or fabricating custom connectors, this Y-shaped harness splits one Deutsch DT input into two fully sealed DT outputs. That saves time and preserves factory wiring integrity while keeping all connections water- and dust-proof.

• Plug-and-play replacement—no cutting or soldering required
• Maintains sealed DT connection integrity with IP68 rating
• Two outputs let you run dual fixtures from a single feed
• 19.6-inch leads provide flexible routing options

What electrical and physical specs should I expect?

The harness is designed for 12V systems and supports up to 300 watts total, using 20 AWG copper conductors for reliable current flow. The combination of ABS and molded plastic housings resists corrosion and mechanical wear, while the overall length gives installers room to position lights without tension on the connectors.

• Rated for 12V, maximum 300W total power
• 20 AWG copper wire for dependable conductivity
• ABS and plastic molded bodies for durability and corrosion resistance
• Overall length approximately 19.6 inches per harness

Will this work with my existing lights and DT connectors?

The CADUFUELLY adapter follows common Deutsch DT connector pinouts and is compatible with most light strips, fog lights, chandeliers, work lights and off-road lamps that use DT-style plugs. Because it’s non-destructive and designed to OEM dimensions, it fits into many vehicle OEM harnesses where a DT plug is present.

• Compatible with many DT-equipped lighting products on the market
• Swap-in design matches factory connector specification
• Useful for aftermarket add-ons and retrofits without harness changes
• IP68 sealing keeps connections reliable in wet or muddy conditions

How durable is the harness for outdoor or heavy-duty use?

The combination of robust ABS/plastic housings and copper conductors gives the harness mechanical strength and long-term conductivity in demanding conditions. Its IP68 waterproof rating protects pins and contacts from immersion and contaminants, making it suitable for off-road, marine, agricultural or construction environments.

• Molded housings resist knocks, vibration, and UV exposure
• IP68 sealing prevents water and dust ingress into connectors
• Copper wiring maintains conductivity under repeated use
• Designed to withstand heavy-duty 12V lighting loads up to 300W

Who this is for: installers, mechanics, fabricators and vehicle owners adding or expanding auxiliary lighting who want a quick, reversible and reliable wiring solution. It’s well-suited for off-road vehicles, trucks, boats, construction machinery, and hobbyist builds where retaining factory connectors and weatherproof performance matters.
