There are four basic styles of brake controllers. The first style is a timing activated brake controller. This control works with your brake switch to activate the trailer brakes at a predetermined amperage output. It can be mounted from anywhere and generally will be used for a short hauls, or a low weight capacity trailer.
Trinidad was incorporated in 1870 as a City of the State of California, USA. Trinidad resident Henry A. Boyes was a First Sergeant with the Fifth Marines in World War II; his service was described by Eugene Sledge in the book, With the Old Breed: At Peleliu and Okinawa.
Trinidad was first explored by Spanish and Mexican traders, who liked its proximity to the Santa Fe Trail. It was founded after coal was discovered in the region, in 1862; this led to an influx of immigrants, eager to capitalize on this important natural resource. By the late 1860s, the town had about 1,200 residents.
