GM-GMC: Spark plug wire sequence, firing order, plug wires

Question
Can you tell me what the sequence of the sprak plug wires in the cap is?
 I have 3 wires and 3 places marked on the cap. I just need the rest or the sequence.
 I have the #2, next I have the #4, then #3.......thank you

Answer
Generally speaking the #1 wire will be marked on the cap.  The wire sequence then follows the firing order in the direction of the distributor rotation.  Not knowing what engine or vehicle you are working on makes it impossible for me to tell you the firing order.  Usually you can find it in the casting on the lower intake manifold.
If you have a small block (305/350) the firing order is 1-8-4-3-6-5-7-2
Hope this helps.
