YnZ's Yesterdays Parts offers its customers over 50 years experience in
manufacturing wire harnesses for antique and classic cars and trucks.

Family Owned & Operated
Our business resulted from our own experience in restoring antiques and classic cars. We give our customers the same personal service and quality product we appreciate in our own restoration process.

Thousands of Original Wire Harness Patterns
We have thousands of original wire harness patterns in our catalog, for all makes and models. Since we use an original wire harness as a pattern, we can guarantee our product to fit perfectly.

Exact Duplicates of the Originals
The wire harnesses we manufacture are exact duplicates of the original. We use original type lacquer-coated braided wire. Wire colors will match your factory specs, and all original style metal terminals are soldered when applicable. Wire harnesses are covered with our own cloth braiding machines, sealed in a rubberized vinyl wrap or with auto loom like the original.

Simplified Instructions
Each wire is numbered, and includes our unique corresponding instruction sheet with illustrations. We also have a "service-after-the-sale policy", which enables an easy installation, even for the "first-timer"

If Its Not Listed in our Online Catalog
Almost any wire harness can be made from your complete original. If you do not see your car listed in our catalog; simply remove your original wire harnesses (tagging as many wires as possible) and we will duplicate it, wire for wire. Upon receipt of your wire harness, we will give you a price quotation and delivery date.

Custom Manufactured Wire Harnesses
Do you have a limited production or custom vehicle? YnZs can provide a custom manufactured wire harness for your vehicle. We can custom engineer a wiring solution for:

  • Limited production vehicles
  • Replica Cars
  • Kit Cars
