(5) Splice Location C
(6) Splice Location BIllustration 3 is an example of a template to help create each harness.Wire lengths vary, the beginning single wire lengths are staggered to minimize the bulge of wires in one area of the harness due to the splices. This also drives landing wire lengths to vary accordingly Wire connections are to be position to position. Example: socket 1 to socket 1 to pin 1 for each of the 3 connectors.The 3 cables straps tied together can help with wire routing to the 3 connectors.ECM to Overmold 120 Pin Test Harness
General information for the 120-Pin Y- Harness between ECM, Overfoam Harness, and Test Harness.
ECM-1 through 120 = Connector to ECM positions 1 through 120
Over-1 through 120 = Connector to Overfoam Harness positions 1 through 120
Test-1 through 120 = Connector for Test Instrument positions 1 through 120Because there are 120 splices needed for 120-pin Troubleshooting Harness, the splices have been broken out into 3 locations - reference slide 4 for general layout.
Location A Splices are on positions 31 through 75 - connector to ECM
Location B Splices are on positions 76 through 120 - connector to Test Instruments
Location C Splices are on positions 1 through 30 - connector to Overfoam Harn
