Here are some places you *might* find some information, but be prepared for incomplete diagrams or potentially inaccurate information:
* Online Forums: Search forums dedicated to Dodge trucks (e.g., Dodge Ram forums, truck enthusiast forums) using specific search terms like "1986 Dodge D150 wiring diagram." Users might have shared partial diagrams or have helpful advice. However, verify any information found here with multiple sources.
* Used Car Repair Manuals: Check used bookstores, online marketplaces (like eBay), and used car parts stores. A Haynes or Chilton manual for a 1986 Dodge D150 will likely include wiring diagrams. These are not free, but usually much cheaper than new manuals.
* Local Libraries: Some libraries have automotive repair manuals in their collections.
* Online Parts Websites: While not explicitly offering free wiring diagrams, some parts websites might offer schematics as part of their parts ordering process. You might need to look at diagrams for specific components.
Caution: Be extremely careful using information found on free online sources. Inaccurate wiring diagrams can lead to significant damage to your vehicle's electrical system. If you are not comfortable working with car electrical systems, it's best to seek professional help. The cost of a professional diagnosis and repair might be less than the cost of fixing mistakes made from using unreliable wiring diagrams.
