68 440 plug wire routing

[Macdon221]

Hey All,

Please don’t beat me up. Lol. I am relatively new at this MOPAR game but love restoring things like the way it was. Or close as possible. I have traditionally been an airplane/motorcycle guy...but forging into the mopars.

I am looking for insight on the correct, or most accepted way of routing the plug wires through the plug wire brackets on the engine. I have a few brochures/original literature home that has engine photos...and surprisingly they match each other. They are not the same photo. But can only see the top brackets and not the bottom of the passenger side or drivers side. See photos below of the vintage literature.

I have combed the FSM but see nothing.

Can anyone help or point me in the right direction?

Here are some other pictures I got off the web to help you out.

So it’s the plug wire routing though the “P” bracket on the ‘68 that I am looking for. Great info and diagrams there BeepBeepRR...very appreciative.

The right rear plug bracket in the last pic is installed incorrectly...

Perfect!

So it just needs to rotate.. Correct bracket but wrong orientation?

 

[dadsbee]

Needs to be flipped.. correct.

From my X..

Any photos of proper wire routings (what wire goes in each slot) through these brackets on a 68 440?

The top pictures of the actual engine should be pretty close over the years.. I was not alive when these cars were built so ya kinda have to rely old the older gents and the photos. But the pictures above should be relative because they only fit into the notches in order. If you overlap then you have a mess. You can see on 1,3,5,7 the go from 7 to bottom to 5 next slot up and so on it just makes sense. If you took number 7 wire and stuck it into the second slot up the wires would overlap and look goofy.

Assuming this is the bracket you are talking about. It looks like number 2,4,6 would be the wires that go into the bracket, since 8 goes over the valve cover and around to the rear.

And your firing order on your cap would be 18436572 Only one of the wires would be on the valve cover side of that bracket and the other 2 would come from the water pump side of the distributor.

When you route the wires off of the cap in order individually. Just by process of elimination based on length of each wire you can figure it out.

Here this might make sense.

That is what I was looking for. Thanks so much.

Here's a few of mine after the rebuild. Maybe this will help

One from the drivers side

Maybe I have mine wrong, but it was my understanding that the front "L" bracket was to hold the wires OFF the block, not against it??!!

There is very little room between the L bracket and the rear of the power steering pump reservoir. This keeps the wires neatly behind the pump, while directly inline with the wire loom nearest the ID pad.

Okay, I figured like every other bracket it was to keep the wires OFF the block and not get heated and go sparky sparky..
