John R. Thomas 0 Report post Posted May 19 I am a long time member of the Milwaukee Fire Historical Society. We own several fire trucks to include shop built, Peter Pirsch and a 49 Mack model B open cab pumper. It is currently in a local body shop. It will need a complete rewiring. I owned a 55 Peter Pirsch pumper for 10 years. Compared to a commercial truck / car, the wiring was straight forward / simple. Where does one obtain wiring diagrams? Board members directly responsible may also inquire. Assistance is appreciated. Share this post Link to post Share on other sites
j hancock 8,502 Report post Posted May 19 B's started in 1953. Maybe an L model? Here is a pdf of a commercial B wiring diagram. The link will get you there. Obviously there will be some fire only wiring that will be specific to your truck vs. a commercial chassis. Share this post Link to post Share on other sites

Board members directly responsible may also inquire. Assistance is appreciated. Go into the BMT WIKI section (enter through the "BMT WIKI Button" on the header.) You'll find B model wiring diagrams in the Antique & Classic Mack Info section Edited May 19 by 41chevy Share this post Link to post Share on other sites
