Show me your spark plug wire routing

This is how I've always done mine.

let's see yours

Follow the arrows on the valve cover. 4123 on the coil pack. That's what I would do.

Good luck.

I don't think he was asking what order to put them in..

I route mine like stock under an SS Valley cover, and then to the packs on the firewall under the IM

I just wanted to see how everyone else routes their wires

When I was learning about car basics, a while ago, I remember something about not crossing spark plug wires. You do not want to wrap them together, braid them, or over lap them. If I remember correctly it has to do with voltage/current jumping crossing, it will ground out to through tthe weakest point. It has to do also with induction, the eletromagnetic field cause by one wire firing can induce an spark in the other.

Its been a wire since I had to look this up or remember it, as a rule of thumb I have never crossed them when wiring up my engine bay. I do follow those arrows and keep the wires separate. Also use some spark plug wire separators, like this:

I have seen seen a members picture on here of his valve cover, in the spark plug area, he has barriers set up using the existing bracket place in the valve cover. Its hard to describe, but it allows the wires to be separate and also kept them organized. I cant find the picture right now sorry.

Please correct me if i am wrong, like I said, I am recalling this information from a while ago.

agentorange - You're correct, you do not want to cross them perpendicularly.


EDIT: I was wrong. Steve is correct, getting them to cross at as close to 90* cancels out the interference. Running them parallel will cause issues, since the magnetic fields will interfere and cause magnetic induction. That's why many wires run in cars are wraped/spiraled around eachother. To cancel out the magnetic fields.

Please let me elaborate:

Looking at the OP picture the cylinders go like this: 4 3 2 1

Cyl 4: Route the wire following the arrow next to the spark plug hole to the back of the valve cover and into the far left coil tower.
Cyl 1: Route the wire following the arrow on the valve cover into the second from left coil tower

The wires don't cross.

Cyl 2: Follow the arrow on the valve cover and go to the third coil tower from left
Cyl 3: Follow the arrow on the valve cover and on to the fourth coil tower

The wires don't cross.

Very simple.

Good luck

I don't think y'all are understanding what he is asking. I'm pretty sure this is a fashion thing. He wants ideas on different ways to make the wires look good.

 

[Colt4G63 also]

I run mine the way Mitsubishi intended. Has someone discovered a better way?

There is actually a reason for the arrows on the rocker cover. It's to minimize the chance of inductive crosstalk causing misfiring. If wires have to cross you want then to do so as close to 90* as you can for the same reason. Wires running parallel to each other are most likely to have inductive coupling.
