Ignition wiring sanity check

[vex]

I'm getting ever closer to installing my stand alone (in fact I'm planning on wiring the power side of things tomorrow and crimping the cannon receptacle): I'm installing the quicksilver coils and want to wire them up on a plug prior to full installation. The trouble is they have no documentation that is sent with them. As such here's what I do have:



I have 5 wires coming off from the ECU that will be connecting to these. 4 switched grounds (one for each coil) and a 12v switched source (don't worry it's relay'd).

My thinking is this:

A - 12V+ switched
B - Switched ground wire
C - Chassis Ground
D - Chassis Ground (or should I really run a wire to the battery ground?)
E - 12V+ Battery

Is this wrong, or is there a better way to wire this up? Thanks.
