I accidentally rearranged my ignition coils and need to

Customer Question

I accidentally rearranged my ignition coils and need to figure out how to put them over the correct spark plug on my corolla 2000
JA: Have you checked the battery lately?
Customer: No, but it’s running fine
JA: Are you fixing your Corolla yourself? What have you tried so far?
Customer: Yes, I’m working on it myself, I haven’t tried much so far, I removed the valve cover and realized that I didn’t organize the ignition coils and forgot which goes where, I don’t know how to figure out which goes where
JA: Anything else you want the mechanic to know before I connect you?
Customer: No

Hello I will help,

The wiring to the coils lays down in the valley and is only long enough to reach each coil. It does not matter which coil goes in which spark plug hole. They are interchangeable.

Let me know how I can help
