MSD Ignition Help

[North Coast Cab]

Trying to get my MSD Ignition and Timing Control wired and set-up. Here's how I have it wired so far. I ralize there are tons of posts on this, but Ihave no factory wiring harness so I'm wiring from scratch.

MSD6AL
Big Red = + Pos
Big Black = - Ground
Small Red = + Pos
Orange = Coil +
Small Black = Coil -
Mag Pick-Up = Not Used
MSD 8680 Timing Control
Black = - Ground
Red = MSD 6AL Red +
Yellow = White from MSD6AL
White = ??
Mag Pick-Up = Not Used

Distributor
Green = ?
Voilet = ?

Thank you, John
