Wire number 242 on a Peterbilt truck is typically designated as a power wire, which connects the truck’s main ignition switch to the fuse panel or other essential power circuits. The number 242 indicates its function related to power distribution, and additional digits following "242" are often used to differentiate between individual circuits that originate from or branch out to various power-related functions.
This standard practice in Peterbilt wiring helps technicians identify and troubleshoot issues in the electrical system more efficiently, as these numbers correspond with specific wire diagrams in the truck’s service manual.
