1968 Plymouth Barracuda Progressive Restoration Part 2

If your fuse box terminals are corroded, they can be a pain in the butt to get clean while still in the box. You can either carefully take the terminals out from the back of the box, or you can lightly bead-blast the fuse terminals while in the fuse box to remove any corrosion if they are going to be reused.

The blue wire with the yellow end is the fusible link that protects the entire system from overload and fire. Normally, cars use a 10-gauge power lead and a fusible link that is four sizes smaller (14 gauge). This is a special wire that has insulation that allows oxygen in so the wire will burn when it gets hot. If you experience a bad fusible link, or you know it's bad, under no circumstances should you replace this link with a common wire. Use only another properly sized, fusible link.

If your existing harness is beyond repair, or you don't even have one, all you need to do is make a phone call.

Made specifically for each car, the YearOne harness is simply "plug and play."

The connectors come pregreased, so they are literally ready to install. Notice the open slots. Often, depending on the application, this will be the case, which will allow you to add additional circuits that might be specific to your car.
