A thermal management system for an exhaust aftertreatment system of a vehicle, the thermal management system comprising:

• a heater configured to heat a component of the exhaust aftertreatment system;
• a heater control unit electrically coupled with the heater;
• a wire electrically coupling the heater with the heater control unit;
• and
• a cable support including:
• a first bracket configured to couple to a lateral outer surface of a chassis of the vehicle;
• and
• a second bracket coupled to the first bracket and configured to extend (i) along at least a portion of a longitudinal length of the chassis and (ii) beneath the chassis, the second bracket supporting at least a portion of the wire.

A fire fighting vehicle comprising:

• a chassis defining a longitudinal length of the fire fighting vehicle;
• an engine supported by the chassis and configured to produce exhaust gas;
• an alternator mechanically driven by the engine;
• a thermal management system including:
• a first housing including a first housing inlet fluidly coupled with the engine and configured to receive the exhaust gas;
• a second housing including a second housing inlet configured to receive the exhaust gas from the first housing;
• a first heater coupled with the first housing;
• and
• a second heater coupled with the second housing;
• a cable support including:
• a first bracket coupled to a lateral outer surface of the chassis;
• and
• a second bracket coupled to the first bracket and extending (i) along at least a portion of the longitudinal length and (ii) beneath the chassis;
• and
• a first wire and a second wire electrically coupled with the alternator and the first heater and the second heater, respectively, wherein at least a portion of the first wire and at least a portion of the second wire are supported by the second bracket such that the portion of the first wire and the portion of the second wire are positioned beneath the chassis.
