Years-old wiring that has been spliced, modified, is dry-rotted or in generally poor condition could lead to an untimely breakdown or much worse, a disastrous fire. For safety and functionality, replacing your old wiring harness with a new reproduction harness is a very smart investment. Each harness is manufactured according to GM specifications, assuring an authentic look and precise connection to all electrical components. This reproduction harness starts with the correct gauge wire, color-coded to match the factory wiring diagram and pre-attached connectors. The correct tachometer wiring harness will supply power from the main under dash harness to the dash mounted tach harness. Each wire is cut to the exact length required and wiring terminals are crimped-on just like the originals. If specifications call for it, the terminals are also dip soldered to limit resistance voltage loss. Hand-assembly of the harness is completed by wrapping the wires with factory-correct, non-adhesive or cloth woven tapes, where applicable, providing a 100% original appearance.
