How to Identify Your Engine:
1. Look at the engine itself: The easiest way is to check the engine casting number on the side of the block. This number will pinpoint the exact engine type.
2. Check your vehicle's documentation: Your owner's manual or service records should specify the engine type.
3. Check online resources: Use your VIN number on sites like Dodge's website (if available) or parts websites to determine the exact engine.
Once you've identified your engine type (Magnum or LA), you can find the firing order and distributor cap wiring diagram:
* For the firing order: Search online using "[Your Engine Type] 1999 Dodge Ram 5.2L firing order". This will give you a list of numbers representing the cylinder firing sequence (e.g., 1-8-4-3-6-5-7-2).
* For the distributor cap wiring: Again, search online using "[Your Engine Type] 1999 Dodge Ram 5.2L distributor cap wiring diagram". This will show you a diagram illustrating which spark plug wire connects to which terminal on the distributor cap. This is *crucial* for correct operation and often varies even with the same firing order.
Caution:
* Incorrect wiring can damage your engine. Double and triple-check all information before attempting any wiring changes.
* Consider a professional: If you're uncomfortable working on your vehicle's ignition system, take it to a qualified mechanic. This is not a job for beginners.
Do not rely solely on generic information found online. Always verify the information with your engine's specific details.
