This item is used to tow your Military trailer with your civilian truck. This new adapter is manufactured by our electronics division. This would be used when your civilian truck/vehicle has a flat 4 style electrical connector and your military trailer has the standard 12-pin electrical connector. Note that this does nothing to convert voltage. If you have a 12V civilian vehicle and 24V trailer light bulbs, you will need to replace the bulbs with new 12V bulbs. *Product appearance may vary based on supply* Additional Details ------------------------------ Product description: This item is used to tow your Military trailer with your civilian truck.
