So where do the ignition wires go on the distributor cap?
Changing out plugs and ignition wires on my 1973.5T (2.4 liter/CIS) when suddenly I realized I could not figure out where the ignition wires go on the distributor cap! I pulled several off without marking. Pretty stupid!
![]() Anyone have a mapping on the distributor cap of the order? I do not expect Bosch to be thoughtful enough to stamp numbers on the caps by the cylinder firing order like most others. Lends to confusion otherwise. Thanks Bob 1973.5T |

Off the top of my head ...1-6-2-4-3-5. the arrow on the distributor will indicate clockwise or CCW rotation. There is a notch on the lip of the distributor under the cap to indicate where cylinder # is connected.
There is also an engine bay sticker that shows the firing order. Best of luck, Rahl Here is the sticker...don't know if it will show. https://tse1.mm.bing.net/th?id=OIP.M6f71f2fbc19494029c4524a7729ce11ao0&w=140&h=105&c=7&rs=1&qlt=90&pid=3.1&rm=2 |

I have that order by cylinder relative to engine order, but need to map on the distributor cap. That is where my inexperience comes into play.
Thanks |

That is the firing order so, assuming you have a Bosch distributor in clockwise rotation, wires go 1-6-2-4-3-5.
If you are standing in back of your car, cylinders are 123 on the left bank, 456 on the right bank. Cylinders 1 and 6 are the ones closest to your legs on either side. Usually cylinder 1 is marked on the top of the cap. If not, on a Bosch cap it is the one below the right hand clip.

First you need to find TDC on the number 1 cylinder to establish where to place the first wire on the cap.

So starting at 1 go clockwise with 6 then 2 then 4 etc.
If you have a Marelli distributor I think they go Counter clockwise. You can verify by watching which way the rotor goes while cranking the engine. Just to be sure.

I'd still double-check rotation with cap off. Just to be sure.

This should have read: There is a notch on the lip of the distributor under the cap to indicate where cylinder # 1 spark plug wire is connected to the distributor cap. Hope this helps, RAhl |

1 is the first one after the clip.

Thanks.
I found a photo of the cap ignition wire set up and according to the line up, Number 1 is to the right of the retention clip (on the above photo) followed (working clockwise looking down), 6, 2, 4, 3 and 5. I will give it a go.................... Bob |
