What color is the positive wire for reverse lights on a ford e350 van?

There isn't a single, universally consistent color code for reverse lights across all Ford E350 vans. The color can vary depending on the year, model specifics, and even the wiring harness used.

To find the correct wire, you'll need to consult your van's wiring diagram. This diagram will show you the correct wire color and location for your vehicle's reverse light circuit. You can often find these diagrams:

* Online: Search for your specific year, make, and model of Ford E350. Websites specializing in automotive repair information may have them (often for a fee).

* Repair Manual: A repair manual specific to your van's year and model will have detailed wiring diagrams.

* Ford Dealership: A Ford dealership can provide the wiring diagram, though there might be a charge.

Caution: Improperly wiring reverse lights can damage your vehicle's electrical system. If you're not comfortable working with car wiring, it's best to consult a qualified mechanic.
