''Electric'' in this case, refers to simply connecting the BrakeLoc to the engine heat riser valve's control wire and signaling to close the valve. A delay of 2-3 seconds occurs before the valve closes and exhaust backpressure builds to retard the engine revolutions vehicle speed. Automatic transmission equipped trucks have this function combined with the BD AutoLoc and TorqLoc computer. These trucks only require a basic wiring harness.
The BrakeLoc computer is designed to close the heat riser valve on the engine and will maintain converter lock-up until a pre-selected vehicle speed. The BrakeLoc improves retarding horsepower from 5-RHP, when the clucth is not engaged, to 200-RHP when engaged. The amount of retarding force is 30% less than vacuum engaged BD vacuum engaged brake and 10% of the stock heat riser valves that stick or bind.
WARNING: Motor vehicles contain fuel, oils and fluids, battery posts, terminals and related accessories which contain lead and lead compounds and other chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. When being serviced, these vehicles generate used oil, waste fluids, grease, fumes and particulates, all known to the State of California to cause cancer, birth defects, and reproductive harm.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
