Default Wiring Q: Accel Dual Sync to FAST XFI

I need a quick sanity check on hooking up an Accel Dual Sync distributor to a FAST XFI box. I would be running the new FAST distributors but Hogan's already made an intake (3 actually) using an Accel piece and a FAST distributor is about 1/2" taller than the Accel and will not clear the throttle body. These are Fords by the way, hence the intake to distributor interference issues.

I have another FAST dual sync distributor for reference, it requires a +12V input, a ground hookup for the wire shielding, and then the plug has 3 wires: 1 for cam signal, 1 for crank signal, and 1 for signal ground

The XFI Cam Hall plug has the following connections:

Yellow/black stripe goes to cam signal
Brown/white stripe goes to crank signal
Black/white stripe is signal ground

The Accel distrubitor has 2 3-pin weatherpacks coming out, each with red, white, and black wires, plus a shielding ground for each signal wire.

Looking at the circuit board inside the Accel I'm fairly sure that each red wire gets a +12V input, the black wire from each weatherpack needs to be tied to the black/white ground wire on the XFI harness, then the red wires for each plug are the respective signal wires (cam & crank.)

Am I correct here? I don't want to fry anything.
