To find the correct color, you must consult a wiring diagram specific to your truck's year, engine, and options. You can typically find these diagrams in:
* A repair manual: Haynes, Chilton, or a factory service manual for your specific 1991 S10 will have detailed wiring diagrams.
* Online resources: Websites like AutoZone, Advance Auto Parts, or others often have free wiring diagrams searchable by year, make, model, and engine. However, ensure the website's information is accurate and trustworthy.
Attempting repairs based on generalized color codes can be dangerous and may lead to damage to your vehicle or even injury. Always use a reliable wiring diagram before working with your vehicle's electrical system.
