Powermaster one wire alternator trouble
1977 Ford F250 Ranger - 460CI motor rear wheel - HELP!
Just installed the one wire alternator " 8-47141 Natural Ford Upgrade Alternator" from Powermaster - Install was easy, removed old alternator and voltage regulator and all of the connection points (two or three go to the starter solenoid, one to horn). Ran a 6 gauge power wire from battery to the back of the alternator, and tightened everything up, reconnected the battery cables which are fairly new. NOW I don't have any power at all. No headlights, no ignition, no beeps, clicks or whistles. NOTHING!...I don't get it! I have power to the battery side of the starter solenoid, but nothing else. I had a new starter solenoid for future issues, so I put that on as well, no luck! I know its something stupid, but Im at a complete lose. The battery is 100%.
Any Ideas?

"..420"? Does that refer to marijuana use? If so ya might wanna stop smoking that crap because it destroys brain cells.
A black wire with a yellow trace supplies power to the cab (and the ignition switch).

no the "420" refers to a Sony Trinitron Mdl#G420 Monitor I had about 18 years ago. funny part is I never heard that before until about 3 years ago...but after having a email that long i just stayed with it. HUGELY against drugs!...but that's a different forum.... So what would be the cleanest way to hook that back up? Should I splice a new wire for that and the horn?
Thanks so much for the responses..I knew it was something simple, but them again it always is!! thanks guys, going out now to retry!!

These images are from the 3g megathread for your guidance to restore your wiring;
You'll likely find that the VR harness is waaaaay long. Here is a modified (shortened) harness.
And a guide for the wiring at the solenoid:
