QUESTION: do you know where I can find a diagram. the wires that were on my truck were 2 different brands and lengths but the firing order was correct
Answerim real sorry about the delayed response i dont get much time.
the length of the plug wires really has no relevence to the order because different plug manufacturers make them dif lengths.. you have to get the firing order from the parts store they have them all on file.
