Due to modifications and production changes there were a number of different wiring diagrams released for the the B10M Mk I. I can only assume this Service Bulletin applied from chassis number 1 up to the the release of Service Bulletin 3-37-18.
The table below is based upon information published in Volvo Service Bulletin 3-37-16. The Service Bulletin included the drawing 1137566 P01 for the B10M Mk I. This drawing is basically limited to symbols with component numbers and requires the component description to give meaning to the diagrams. The table below is sorted by the Component Number field and is used to interpret the component numbers on the drawings.
The letter and digit in brackets indicate the box where the component is situated. Connection points marked on the wiring diagrams with a brown arrow are intended for the bodybuilder.
