Since I'm getting the same on both banks I think it's normal
OK that's good. So that tells us there's a complete circuit from VS42 through each coil and to the DME. Did you try if there's consistent voltage while giggling the harness at various spots?

Another thing you may want to check is to diconnect the coils one by one and see if their respective wire still has 12V at the DME. To use your example, disconnect coil 1 and check green/blue for 12v. It shouldn't have any. If it does, it's shorting with another wire that carries voltage.
