Because of the inherent danger involved, wiring is the most loathed of all building tasks. It doesn't have to be that way. Unlike vintage cylinder heads, wiring (along with fuel tanks and lines, brake lines, brake master cylinders and tube tires) is something that no one should ever try and reuse in a car build. Old cloth wrapped wiring is something that needs to stay in the past. Here's the best modern substitute.

AFTERMARKET WIRING HARNESSES:

A number of companies make a variety of fuse block type wiring harnesses. These harnesses are better in every way to what was used originally in classic cars. Allowing for individual fusing of multiple different systems, will ensure that nothing is ever over loaded or starving for power. This also helps with identifying shorts and isolating sub systems for repair.

The best part about these wiring type of wiring harnesses is the fact that the wires function is printed on them. Spaced out in 6 inch intervals, this is the best advancement in automotive wiring since coated wiring. This printed identification allows you to run the wires as a bundle. Running wires as a bundle, as opposed to one at a time, saves hours in the installation process. It also will allow you to easily identify, with absolute certainty, what a wire does after being ran.

I hear what you are saying, "I don't want that modern looking rainbow wire under my classics dashboard!" Well Summit Racing has got you... covered. A few years ago they introduced a type of heat shrink tubing that looks like cloth style wiring. This will allow you to have safe, modern wiring in your classic auto, but not distract from the cars beauty. This stuff is great and when purchased in different colors, can still help you keep wires separated and easily identifiable.

IT REALLY IS THAT SIMPLE!

So whats the secret to wiring a car in a weekend? A modern fused wiring harness. One of these units can help even the most inexperienced classic car owner, perform the once complicated task of wiring an entire car. These manufactures even have some harnesses made for specific cars and trucks. This will eliminate some to the early logistical issues experienced with universal harnesses.

Of all the things the aftermarket auto parts world has created, these wiring harnesses are one of the best!

Keep on Cruisin'!
