* Online Automotive Repair Manuals: Websites like ChiltonDIY and Haynes.com often sell downloadable repair manuals. These manuals usually include comprehensive wiring diagrams. Be sure to specify the exact year, engine size, and any options (like power windows, sunroof, etc.) when searching.
* AutoZone, Advance Auto Parts, or similar: These auto parts stores may have access to wiring diagrams through their online resources or in-store computer systems, though availability varies. They usually require your VIN (Vehicle Identification Number) for accurate information.
* eBay or other online marketplaces: You might find a scanned copy of a factory service manual on eBay or similar sites. Be cautious of the quality; some scans can be blurry or incomplete.
* Local Auto Repair Shops: A local mechanic might have access to wiring diagrams through their subscription services. They may be willing to help you, especially if you plan to have them do the work.
* Your local library: Some libraries have access to automotive repair information databases.
Important Considerations:
* VIN number: Having your vehicle's VIN (Vehicle Identification Number) is *essential* to ensure you get the correct wiring diagram. Minor variations in options and trim levels can significantly alter the wiring.
* Specificity: Be as specific as possible when searching. Specify the year (1995), make (Pontiac), model (Transport), engine size (e.g., 2.0L, 3.1L), and any relevant options.
* Factory service manual: A factory service manual will be the most complete and accurate source, but it's usually the most expensive option.
Remember to always disconnect the negative battery terminal before working with any automotive wiring to prevent accidental shorts or damage. If you're not comfortable working with car wiring, it's best to consult a qualified mechanic.
