COP Coil-on-Plug ignition [Merged 1-8]

[dave99gst]

im thinking the colors listed are 2g colors. ( i dont really know for sure, ive never seen the need for COP other then the "bling" factor.
Can you look at a friends 2g coil and compair colors?

 

[DarthBulk]

I took my COP apart and made a wiring diagram of how it was wired If you can wait until I get home from work today, I can scan it and post it up here.

 

[Blackmitzu]

That would be awsome.

If you don't have an ignition amplifier, you're downgrading your ignition system by running the COP setup.

 

[DarthBulk]

Here is the sketch of my COP wiring. I was curious how it worked, so I took mine apart and made this diagram of it. If you have any questions about it, feel free to ask me. I free hand sketched this while holding the paper up against the side of my car, so don't laugh at my sketching skills

 

[DarthBulk]

Oh, those wire colors are the colors on the COP, not the car. If you give me a little while, I can check which wires I matched them to on the car. I did the same as you, I cut the plug off my old coil pack, and wired it onto the COP so I could just plug it into my harness. It works fine.

 

[Blackmitzu]

What kind of cop setup do you have? Bushur? I dont have a green wire the pigtail i cut off of my stock coils.

 

[Blackmitzu]

I have a red wire, white wire, and a black with a white stripe.

 

[Blackmitzu]

Also did you have to cut a little off the plug boots on the coils, or did they come already cut ? I see that i need to cut a little off the boots and was wondering as to how much i need to cut.

Im actually in the process of installing my msd as well.

 

[DarthBulk]

My COP is a Switzer, I believe. My coils came already installed in it. Those wires colors I have listed are on the COP itself, from Switzer. They don't match the car wiring harness colors...give me a few minutes, I will go brush the one foot of snow off my car and check which wires from the car I connect to the colors I have listed in the diagram

 

[DarthBulk]

Ok, here is the wiring as I connected it to the car. I changed the wires to match the colors in the car's wiring harness. I hope that helps
I had to brush a foot of snow off my car, and inspect the wiring in the dark, to find this

 

[Blackmitzu]

Wow , thanks dude. That really kicks azz that you did that to help a brother out.

 

[DarthBulk]

No problem, I know that when I was trying to set up the COP system, I couldn't find much help on actually wiring the coils in. I'm just glad to help when I can

 

[Blackmitzu]

Does anyone know what each wire is? Power ground? signal wires? I showed the diagram to my freind and he said it was wrong.

 

[DarthBulk]

This diagram is straight from a commercial COP system that I bought. It is on my car, running right now. If you look at the wiring diagram, the 1 and 4 coils are wired in series, and the 2 and 3 coils are wired in series.

 

[Blackmitzu]

Ok, i will wire it the same way as yours. Do you have a cid ignition as well?

 

[DarthBulk]

Ok, i will wire it the same way as yours. Do you have a cid ignition as well?

No, I currently don't have one of those. It is on my list of things to do...

 

[jasonlee]

here is what I did mine by.. not sure if its the same or not...

 

[SFRacingGST]

Was wonder how i would go about checking my base timing with my coil on plug setup?

 

[yukondoit]

Just as you would normally, just clip the timing light to the ground wire of the coil number 1, it should see it. I done this on street bike motors and snowmobile cop system with no problems.

 

[SFRacingGST]

cool, thanks for the quick reply, im going to need that info next weekend when i start it up but i just wasn't sure where to get the firing signal from since there are no more wires.

 

[SFRacingGST]

After starting it up with the coil and wires and getting my bases down, i put my coil on plug setup on and my car wont start. I verified that i plugged it in, and i know the rubber boots went on the plugs, then the spring seated properly. Any suggestions? Do i have to unclick invert CAS in link? Gap different?

 

[TALONTRAX]

The cop. should be a plug & play deal, unless the trigger wires are accidentally inverted (resulting in reverse firing order).
I would re-check your wiring for correctness, or bad connections . . .

I had mine wired with 2 wires backwards, when I bought it was just 3 wires 1&4,2&3,and 12+.

I had 1&4 wired with the 12+ and the 12+ wired as 1&4, lets just say running on 2 cyliders isn't fun....

I called up Buschur Racing(from where I bought my COP setup) and they gave me the correct wire color codes....

Now that I switched my 2 wires runs like a dream, fires beautifully, and a much, much, cleaner look
