Will this work?
Basic main circuit and ignition ('70-'71)
You won't have a column connector. With the MSD you can connect the two Ign circuits if you don't have a ballast.
The smaller gage red wire is only powering an on-off relay inside the box.
Whatever I copied originally showed a 12 gage wire from the alternator output. In your setup, 10 gage would not hurt. '81 truck prob was 10 gage already if that's what you're using.
