Proper cut ignition wire lengths?

I have just purchased an Accel unassembled braided spark plug wire set.
This kit consists of 4 long wires of unequal length that are supposed to be cut up to 8 wires to fit a Chevy Small block.

Since the 4 length are unequal, are each of them supposed to be cut in 2 EQUAL halves, or what? I don't have an old wire set to compare.
I would hate to come out too short on the last one because I'd cut something wrong on the first ones.

I asked Summit customer service the same question. They answered that I could cut just like I wanted...They probably didn't understand my question.

Hopefulle someone here do it?

Don't just cut in equal lengths, you will end up short somewhere unless they are actually so long as to not matter. You are going to have to plan out the routing a bit, some of them will be cut to one long wire and one short wire. I can't help you beyond this, just use common sense and measure twice, cut once.

Most u-terminate wire sets come with 8 wires, all longer than they need to be, with the spark plug end already installed, you just cut to length and add the distributor end and boot.

Are you sure your set isn't missing 4 wires?? How long are the 4 you have?? Are any of the ends pre-terminated??

Put it this way...the length of your wires have no bearing on how quickly they fire.....unless they were about a 1000 miles long.

It sounds like you got a stainless steel braided wire set- am I correct?

If so, I seem to remember from making up a set for a buddy that the wires were supplied w/2 "finished" ends per wire, that is, both ends of the wire has the braid ending before the end of the wire, and you are to cut the wire across the braiding for the 'other' end.

You will need to wrap masking tape around the wire before you cut it. I used a cable cutter- a sort of bypass cutter for stranded wire- that cuts cleanly. Another option I don't mind using, is to wrap the wire w/masking tape and use a Dremel fiber cut-off wheel to slice the wires.

But you will need to plan for the correct lengths so as to get the most from the wire supplied. I recall having more than enough to do the 400 Pontiac I was wiring.

There were also metal "grounding straps" that the wires (by fours, IIRC) were clamped into and the "pigtail" coming from the clamp was to be grounded to an engine fastener like the valve cover bolt, etc..

There was a 2-piece terminal crimping tool meant to be used in a vice for the one side, the other side held by hand and was hit w/a small hammer to do the crimping.

All in all, they looked fine, but I also seem to remember the wires being replaced- I just don't remember exactly why.

You are correct, and thank you. your inputs are very valuable, as there are absolutely no instructions enclosed in the package.

One other thing- and this goes for pretty much ANY wire set you may make up yourself: Remember to put the boot on the wire BEFORE you crimp the terminal!

If you have some, spray silicone works great for easily sliding on those boots. Dielectric grease or silicone grease will work too, just a bit messier.

Try not to nick the innermost conductor when you go to strip the covering from the wire. I think I remember there being shrink wrap to cover the ends of the braid where they are cut. And that the braid should be cut some amount of distance from the terminal end- I'm sorry but this was in about '90 or so, my memory of it all is a bit hazy.

Have you looked online for the instructions? Maybe by using the Accel part number you can scare them up.

The more I think about it, the more I think there were all 8 plug wires, terminated on one (distributor) end- NOT just 4. This may have changed- but if it DID, there should be terminals on BOTH ends of each wire. If not, you were shorted or got the wrong wire set- like for a 4-cylinder application.

Good luck.

Hi and thanks for the link!
I'm pretty sure my 4 wires are ment to be cut. they are way too long to be used as is and hey have terminals w/ blue 90 degree boots in both ends. In the box there are 8 more loose terminals and 90 degree black boots.
In the product descrition for the item number it states that this kit has blue boots for the plug end and black boots for the HEI end.

OK, you are good to go- my concern was if the wires weren't terminated on BOTH ends- but as they are, all is well!

I honestly do not positively recall if I got 4 wires like you did, or 8 separate wires- but I suspect it must have been 4, like your set.

Good luck.

A friend of mine had a set on his El Camino, sorry to say they looked terrible, the braid catches all the underhood crud.
