Coverage by product
| Product or component | Coverage |
|---|---|
| All Diode Dynamics products: defects in materials and workmanship | 3 years |
| Stage Series and Elite Series lamp assemblies and lamp mounting brackets (functional failure; wiring, harnesses and lens covers excluded after year 3) | 8 years |

What's covered
- Defective products are replaced with the same item, or a comparable one if it's been discontinued
- Diode Dynamics may replace just the failed component
- Finish defects caused by manufacturing, during the first 3 years
- Moisture beyond normal condensation that points to a seal failure, at Diode Dynamics' discretion
- Free tech support for the life of the product, even after the warranty ends
What's not covered
- Normal condensation, and paint or coating wear from regular use
- Installation or labor costs
- Improper installation or use, abuse, or opening, rewiring or repairing a product
- Swapping lenses on Stage Series lights voids the 3-year coverage (the 8-year coverage stays)
- Purchases from unauthorized sellers; coverage is for the original buyer and isn't transferable
How to make a Diode Dynamics claim
- Keep your proof of purchase; every claim needs it (gift recipients can register within 90 days of the original purchase instead)
- Request an RMA through Diode Dynamics' returns portal and work through diagnosis with their support team
- Nothing goes back without an RMA number; include photos for moisture claims
- For US customers, Diode Dynamics covers shipping on 3-year claims, plus return shipping for inspection on 8-year and lifetime claims

The Diode Dynamics Stage Series C1R/C2R 10-pin Dual-Output Trailer Wiring Harness lets you run two C1R or C2R LED pods straight off your truck’s 10-pin trailer hitch wiring. It ends in two Deutsch DT outputs, so the pods plug in without splicing into the vehicle harness, and the lights work along with the signals your truck already sends to a trailer.
Why it works
Hitch-mounted pods are only useful if they come on when you need them without a dedicated switch you forget about. Tapping the trailer connector gives you simple, everyday operation: the pods respond to the same circuits a trailer would. The high-capacity 14AWG wiring has headroom for two pods. It is rated from -40°F to 185°F, so a Wisconsin winter is not a concern.
Options
Single-output harnesses run one pod; dual-output harnesses split to two. This one has two Deutsch DT outputs. Match the 10-pin connector to what your hitch wiring uses before ordering.
Fitment
Universal for vehicles with a 10-pin trailer connector. It operates on 9–16V, which covers standard 12V truck systems.
Specs at a glance
- Operating voltage: 9–16V
- Connector: Deutsch DT output
- Outputs: 2
- Wire size: 14AWG
- Weight: 0.7 lb
- Part number: DD4186
Warranty
Covered by Diode Dynamics’ 3-year replacement limited warranty. Full terms are on our Diode Dynamics warranty page, and the rest of the lineup is in the Diode Dynamics collection.

Specifications
Diode Dynamics Stage Series C1R/C2R 10-pin Dual-Output Trailer Wiring Harness FAQs
Which pods does it power?
Diode Dynamics C1R and C2R LED pods — up to two, one on each Deutsch DT output.
Do I need to cut into my truck’s wiring?
The harness is designed to connect directly to the trailer hitch wiring, so pods plug in rather than being spliced into the vehicle harness.
Single or dual output?
Dual output runs two pods. If you only run one pod, the single-output 10-pin C1R/C2R harness is the simpler choice. Call or text the real humans at NVMOS, (920) 249-7744.
