It’s just wire, right? Wrong.

“It’s just wire, right? Why do your Classic Update harnesses cost more than a universal part from brand X?”

There are a few reason for this, some of which we have covered in other entries or frequently asked questions, but many customers don’t necessarily realize how much labor it takes to build a vehicle-specific kit, or in our case at the time of this writing, about 50 different kits.

We take time to source original tooling, terminals and connectors for our harnesses. For Factory Fit parts, we have access to original injection molding and GM blueprints required to make a correct replacement.

These are also an important part of the process for both ends of the product line:

This is one of our many terminal machines. We have rows of them, with each one being responsible for a different style of terminal.

This is Asa…we only have one Asa. Here he’s creating a connection for the fuse box in one of our Classic Updates. Our terminal machines save quite a bit of time, but it’s still a surprisingly manual process to turn a bunch of rolls of wire into a functioning path for electricity. Each connection in a harness starts like this:

In the photo above, we are terminating 3 wires for use at one side of a fuse. All three are placed at the appropriate depth in the terminal machine, the floor pedal is pressed, and 3 to 5 tons of pressure are applied to an unsuspecting terminal, insulation and wire core.

6,000 to 10,000 pounds of pressure tend to make a fairly tight connection, but for this circuit we add a little solder to help make sure the key termination stays corrosion free for the life of the harness.

At this point, it’s off to the next section of the build. This piece will eventually clip into place in the back of a fuse panel to supply power to a portion of the dash harness.
