So I bought a 2000 s40 turbo 4cyl that had thrown a timing belt and have been working on bringing it back to life. However I just realized that the conncetors for the coil packs are gone with bare wires instead. I have no idea which wire goes where. I have green and red wires on one side and grey and red on the other. I have searched the internet for a diagram or something to help me figure this out but have had no luck. I even went to my local junkyard to see if they had one I could look at....no luck. I did obtain two of the plastic connectors but they were off of a 5cyl so the colors dont match up. Any help would be great.

I have attached a pic so you can see what im talking about

 

My 2000 S40 is apart right now so I went and took a look. Red is on the left for both connectors. Hope this helps.

 

That does help thank you......I would assume that the green and red goes to the coil closest to no 1 cyl. Is that how it is on yours?

 

Here is a pic for the fuel pressure regulator. You can see the wire colors in the background:

 

That is exactly what I needed....thank you both for your help.
