For 1963 Impala restorers one of the most important safety features your car needs is a rear body wiring and taillight wiring harness system that is in good working order. 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. Late Great Chevy offers the best in reproduction wiring harnesses for your Impala. Each harness is manufactured in the USA 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. 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. Be safe, not sorry with show-quality, correct reproduction rear body wiring and taillight wiring harness in your classic 1963 Impala 4-Door Sedan.
