resistor wires color on 1990 ford e350 van

In the early days of automotive technology, the Ford E350 Van was one of the most popular models on the market. What set this model apart from its competitors was its impressive level of build quality and its advanced wiring system. To ensure that its electrical components worked correctly, the E350 Van utilised a colour-coded resistor wire system.

These resistor wire colours, which are still in use today, are white, black, red, green, yellow, and blue. The primary purpose of these wires is to ensure optimal voltage levels are being delivered through all circuits. As different components require different voltage, the colour-coded wires ensure that the correct voltage can be easily identified and correctly applied.

The 1990 Ford E350 van was one of the first models to take advantage of this colour-coded resistor wire system, which was an innovation in automotive technology at the time. This system made it possible for mechanics to diagnose issues with the van’s electrical systems quickly and efficiently, saving both time and money. Today, the resistor wire colour system is the industry standard for a wide range of automotive applications, offering an effective way for mechanics to identify and resolve wiring issues in a timely manner.
