Quality: Sheyenne Dakota has an exceptional testing procedure. In addition to checking the harnesses against both the customer’s and Sheyenne Dakota’s engineering drawings, the harnesses are inspected at the assembly boards then tested on Dynalab NX Testing equipment ONLY AFTER the harness has been completed. Each harness is then visually inspected to ensure it is in compliance.
