Does anyone know what wire gauge size is sufficient for waste spark coils? I’m wiring up a Holley Terminator X Max to use my waste spark coils. Holley doesn’t make one and I don’t want to chop up my COP harness so I can go that route in the future. Holley terminator uses a 20 ga wire for the COP. Is that sufficient for waste spark coils?

Just a trigger wire correct? That's all I can think of.

I don't have my "stuff" yet but I have this coming which is supposed to make it easier to hook up waste spark. I am below rookie level on knowledge here but... :)

Each coil has 3 wireS, 2 triggers and a power wire. Bought new motorcraft plugs for the coils and it came pre-terminated with wire. The wire that came on the plug is much larger than the 20 ga wire that Holley used in the COP harness that came with my kit. The difference in wire size just got me wondering if it requires larger that 20 ga. Probably overthinking it but that's what I do!!!! o_O

Understand. If I get my sub harness I can check the guage size.

I overthink that stuff too. Can't go wrong with larger ga wire tho‐ so long as the pin will accept it.
