Method of manuacturing a three-dimensional work vehicle wiring harness

A method of manufacturing a wiring harness for a work vehicle using a tool board assembly, the tool board assembly including a tool board base, a plurality of wire supports extending from the tool board base and each having a wire holder on a top end thereof distal from the tool board base, and a plurality of input/output (I/O) connector holders extending from the tool board base and each having an angularly adjustable connector mount on a top end thereof distal from the tool board base, wherein the method comprises:

• positioning a main harness branch of the wiring harness on a portion of the plurality of wire supports;
• routing a plurality of breakout harness branches off from the main harness branch and through another portion of the plurality of wire supports;
• and
• coupling an I/O connector at an end of each of the plurality of breakout harness branches to a respective I/O connector holder of the plurality of I/O connector holders;
• wherein, in routing the plurality of breakout harness branches through the another portion of the plurality of wire supports and in coupling the I/O connectors to the plurality of I/O connector holders, the plurality of breakout harness branches are routed through wire holders at a plurality of different heights relative to the tool board base and at a plurality of different angles relative to the main harness branch, and the I/O connectors are coupled to angularly adjustable connector mounts at a plurality of different heights relative to the tool board base and at a plurality of different angles relative to the tool board base, such that the plurality of breakout harness branches are held at a plurality of breakout angles relative to the main harness branch and at oblique-angle orientations that are non-parallel and non-perpendicular to the tool board base.
