Default Ignition coil wiring help

I am looking to wire in a flame kit. I need to find a wire or connection that powers my ignition coils seperate from the rest of my engine. Does this even exist. I know in the ASD relay pin 87 powers coils, injectors and O2 sensors. I have also seen that in ASD pin 86 only powers coils but I cannot verify this. Anyone have any insight or knowledge into this topic. I am very bad at reading wiring diagrams so I can’t tell. Many thanks in advance

What's a flame kit? Are you dumping fuel into the exhaust, and then igniting it?

Yeah, pin 87 of the ASD relay powers all the coils. Brown wire with white trace. Connector 7, pin 4 on the TIPM.

Does it also power everything else. Is there anyway to seperate it out if it is also connected to other things. I just need the coils by themselves

The wire goes to a splice, and then to the rest of the coils, it also runs a feed back to the PCM, to tell it that the ASD is actually engaged. I don't see anything else on that wire. Looking closer, it splits TWICE there, one lead runs off to another splice, and then to the coils, the other two both go to the PCM......
