quick spark plug wire question

[bryantn13]

I received my 8mm spark plug wires today and was excited to put them in. i removed the old wires and then realized theres number on them

so im just making sure it goes from the driver to the front of car like 4-3-2-1 ?

my #1 wire is the longest so i think this is right.

you may not be able to fit all of the 8mm wires into the factory looms.. but yes, the longest one should be your cylinder 1.

which to be a little more clear is the cylinder closest to the front of the car.

in order of smallest to longest is 3-2-4-1 i installed it like that into the engine and matched numbers on ignition box.

3 of the 4 wires fit in the loom and the 4th i made a hole in the back for just that one.

im gunna start my car i am pretty sure if i matched the wires with the length i should be fine?

[bryantn13]

ok something is wrong. i tryed to start it and it made a nasty noise and did not start

[nyle]

hm. let me go look at mine.

make sure that everything is plugged in really tight

[nyle]

ok. its what i thought. it goes 1-2-3-4, with 1 being most toward the front.

[bryantn13]

omg thank you lemme go change that, btw match the numbers on the ignition box right?

thanks nyle!

[nyle]

yes. i think they go in the same order. it should say on top of your ignition coils. the bmw OEM ones have a little snap on cover thing that has the numbers.

[bryantn13]

got it Runs a lot smoother now thanks again

hahaha glad you got it figured out

[elchicano]

Yea when i first read this i thought mine were wrong. But they are on right in the end, 4 3 2 1.

I did the same thing with a buick once, every spark plug wire was in the wrong spot, that was because of a sh!tty diagram I got off alldata, I was completely sober when I did it

You should mark both end of the cables, before you remove them. Take a piece of tape and wrap it around the end closest to the plug, and the end closest to the coils. Then right the number of the plug on the tape.. You should also note exactly where they plug in on both ends. If you have little tape tags it is easy enough to just snap a picture of them, then you know exactly how to put it back together..

On a 318 it is easy because it goes in order.. But if you deal with an older car with a distributor and a funky firing order, it can get confusing...

That's exactly what had me puzzled when I put my 8mm wires in. On older cars, the distributor fires in a circle, and you take the wires to the cylinders in the order the cylinders fire.

With our cars, the wires go 1 to 1 coil to cylinder, and the coil pack fires in the order the cylinders require.
