I have a quick question regarding the spark plug wires on my 1990 FC. I know the blue capped wires go to the trailing coils, but on mine the leading coils have the blue cap. So someone must have switch them before i got it. Is this going to be ok or something that is going to damage my engine? It seems to be running fine the way they are, but I am just concerned. Thanks

 

The wires are connected to right coil packs and spark plugs its not a firing order issue, just unsure if the spark is different between the wires.

 

what happens when you get different colored wires?..
Color has nothing to do with the wires.The wires may have been switched as they were in better shape.
Look at where they go to.
That is the Main priority.Correct Firing order.

 

Thanks Misterstyx. Always a good help.

 

But if it isn't the right color, won't the electrons get confused and not know where to go?

I just didn't know if they were different voltages haha

 

Yes, that can be very difficult to determine.

More important than voltages I think, is to ensure astrological birth sign compatibility between the wires.
You mix say, Capricorn leading wires with Aries trailings and things will get ugly fast.

 

That's cute..

 

I'd be racial and say only use WHITE wires but I would get PM's from Smurfs.
