Shake rattle and roll

Never would have thought of that. When i routed the plug wires i just tried to make them look nice and keep them off of hot components. I found the article with a lot of detail on how to route them in a factory dodge truck setup. Would I be right in assuming the main point is to keep space inbetween wires and try to keep them from crossing but if they must, do it at a right angle?

I think the goal is to make sure none of those wires touch each other at all. I would bet the coil wire can jump to a wire it is touching and not even go through the cap, and the 8/4 wires and 5/7 wires are sequential which (I guess) make them more susceptible to misfiring. I’ve always heard with the LA to watch the routing of the 5/7 plug wires, but the TSB includes the 8/4 wires and the coil wire.
