Ok I wanna use a msd box with a 7pin computer controlled HEI that uses a remote coil adapter LOL

So I'm gonna run my heavy red/black like normal to the batt
black/orange to the coil like normal
red to the pink HEI key on connector or any key on hot

White to the ??? This is the part I'm not 100% about, there are three wires that run to the coil in the cap and I just need to use one to fire the box since the coil will be hooked up at the box.

Just for examples I am not gonna use either harness

Orange wire from CD to coil +
Black wire from CD to coil -
Black wire in three wire connector to center terminal in cap is ground wire for coil secondary, it must be grounded. Both it and the black wire from the CD box can be grounded to the engine. No other wires connect to coil, no 12V, just orange and black from box and ground the center terminal in the cap.

Wire from module to coil - (brown?) to white on CD box.

LOL I finally emailed msd and they told me to look at the diagram for the HEI modules in their box instructions, so brown. Shows brown and black in the diagram but may work either way.
