What makes the Classic Update series harness kit better than the competition?
The Classic Update Series design philosophy is to build complete “full function” systems and engineer them for easy access, easy installation, and connectivity with common update accessories. All while allowing for future expansion. Each kit is a completely new design engineered around the specifications and physical dimensions of the 55-59 trucks as well as the space constraints imposed by many after market accessories vying for the limited space under the dash. Superior design has given the builder complete flexibility to use original stock switches and components as well as custom update accessories, such as; DAKOTA DIGITAL instruments, heat and air conditioning systems, IDIDIT and FLAMING RIVER steering columns, and late model GM tilt steering columns. The fuse box was chosen for its adaptability in mounting configurations and its ability to handle the increased current loads demanded by power accessories such as power windows, power seats, power door locks, cruise control, etc. It is a proven GM design that incorporates heavy duty circuit bussing. There is no circuit board in this high power fuse box assembly as the potential power demands are too high for a circuit board design. It is this attention to detail that removes the engineering exercise from the builder and makes installation much smoother.
Accessory disconnect provided for connections to power windows, power seats, cruise control, fuel pump, power door locks, extra radio (CB), or optional power accessory.
