Up for sale is a rare and unless I suddenly forgot how to do a good search is rare indeed only one on I can find
, New Old Stock (NOS) Vintage Kelsey-Hayes (KYH) Load Control Automatic Electric Trailer Brake Controller, Part Number 100404A. This classic towing component features a front adjustment dial to control current delivery, ranging from "Min Brake" to "Max Brake."
Because this is New Old Stock, it has never been installed or used. This complete package includes the original controller unit, the original "Kelsey Load Control Installation Instructions" sheet, and the original stamped manufacturer box from the Kelsey Products Division (Romulus, Michigan). It is an absolute pristine find for a vintage truck restoration, classic car enthusiast, or period-correct towing display.
Condition: New Old Stock (NOS). Excellent, unused cosmetic condition with only minor shelf wear brittle pages on instructions from decades of storage. Dial turns smoothly. The installation instructions and wire size selection table are entirely intact and legible. The original non-retail factory box shows typical vintage shelf wear, fading, and aging but is structurally intact with the stamped part number clearly visible. Please review all photos for exact cosmetic condition.
