I’m just not sure which of these wires to hook up where.
Need help with my 1g/3g alternator switch
I’m having some issues with the wiring on my old 1g alternator. Included some pictures for reference. Do I need a new harness or can I make what I have work?

How-to Install a High-Output Ford 3G Alternator into Older Fords
A Ford 3G integrally regulated alternator is the best choice for replacing old 1G externally regulated alternators on amped-up muscle cars.
The cheapest way to get NEW plugs are either from a seller on ebay or these two links.

I have one of these with the 3g kit I bought but my vehicle harness wiring doesn’t seem to lining up with the instructions. It came with the harness above and a regulator.I would get one of these.

The note one and two are confusing me. My harness does not look like the one in the notes . I have a blue wire a white wire and a black wire that is also connected to the ground.

Okay.... and your 3G alternator has a 3-pin plug that goes in the side with a pigtail with a ring terminal that goes to the BAT output post on the alternator?
Should be something like this.... As described elsewhere, I would NOT replace the original alternator output wire (yellow or black/yellow) but add a second 6ga wire with both terminating at a 100A fuse at the solenoid common (like this one... https://www.amazon.com/WindyNation-...?keywords=100+Amp+Fuse&qid=1679407416&sr=8-19). I'd mount it adjacent to the solenoid and supply it from the solenoid common with a short 4ga wire.
Simple diagram, red and yellow can share post on back of Alt, gray/white plugs on back of Alt, red goes via fuse to starter solenoid and then BAT, ggreen, might have red stripe goes to ignition. Optional ground cable….only 2 wires need to leave Alt and run to inner fender…google ASI a plug for the connector…
