An auxiliary-cooled electronics assembly can carry electrical circuit components and cool those components using one or more cooling conduits in the metal extrusion that flow cooling fluid. End caps can be attached to the assembly or the metal extrusion forming a fluid-tight seal enclosing the cooling conduit(s); the caps can include a fluid inlet and/or a fluid outlet for the cooling fluid to enter and exit the cooling conduit(s) and carry heat away from the electrical circuit components. The electrical circuit components can be attached to the metal extrusion and protected by a cover that extends over the electrical components and encloses them under or within. Cooling fluid, such as internal combustion engine (ICE) coolant or lubricant, can be provided to the fluid inlet. The fluid can pass through the cooling conduit and exit the fluid outlet.
