SIERRA Amber/Red-to-Red Trailer Light Electronic Converter – TC43504
The SIERRA TC43504 electronic trailer-light converter allows a tow vehicle with separate amber turn signals and red brake lamps to operate a trailer that uses combined red stop/turn lamps. It is a universal splice-in solution for matching otherwise incompatible tow-vehicle and trailer lighting logic without adding separate trailer lamps.
- Converts separate vehicle stop and turn circuits to combined trailer stop/turn outputs
- Designed for vehicles with amber rear turn signals and separate red brake lamps
- Universal splice-in installation
- Allows use with conventional 4-wire trailer lighting systems
- Useful when tow vehicle and trailer use different stop/turn lamp configurations
Before installation, match the 4-flat connector gender and wire functions to the tow vehicle and trailer, and confirm the trailer lighting system is compatible with the converter or harness configuration.
