hi i was hoping someone may remember an article i read  somewhere a long time age concerning the leads on a y block.the rubber insulator blocks at the rear of the engine which hold 4 leads each had a certain order or position for the leads to go. sounds odd but i need to know that order because  i suspect i have a crossfire issue in that area.the article showed the order they go in to avoid  possible crossfire, hope somebody may remember this and let me know,, cheers
