EQSS publishes all Overwatch Installation manuals on their website via the link -  Overwatch Manuals  

Each of the Installation Manuals has a Harness Drawing somewhere towards the end of these manuals. If an installer or a technician needs to trace harness connection points and wire colors then this drawing is the place to look for answers.

Please locate the installation manual for your particular make and model machine and if you need to troubleshoot your harness; locate the Harness Drawing
