Hi everyone ,
i have to connect the old 66 wiring with the new 3g alt and regulator .
it comes from pa performance , with pigtail for alternator and a " look a like " regulator .
From me comes out only headache , looking at the oem wirings that was spliced and adapted to a different regulator.
the pigtail was missing and now this is the situation . i dont' know how to connect these wires.
try with no lucy to contact pa performance , they give me only info regarding a generic wiring so not useful.
the pigtail on regulators has " i a s f " letters but which colors does corrispond ?
please if someone have this 3 g alt can explain to a dummies how i can fix it ?
i dont know if this connection are in right spot
the yellow wire were not used in the previous regulator , now where it goes ?
the other black red should be grounded .
this is the old connection with alt, . From the new alt , comes out only 1 wire green / red .
thanks if someone knows something

Go to PAperformance.com
Click on Alternator tab
Then, click on Mustang (65-66) alternator upgrade.
Once that opens, on top of the page, click on the Blog tab
When it opens, there's a video link tap, open that and watch how they wire up your 3G alternator....
At the 6 minute point of the video is where you should begin watching....
Good luck

This is the reply from pa performance
We do not have a diagram, but the basic instructions are to put our regulator box in place of your factory regulator box and connect your original field wire to the green wire on the harness we provided. The other 2 wires connect directly to the alternator.
The field wire It is marked “F” on the voltage regulator.
The previous picture says to put green red in the I of regolator
Pa performance says to put the greed Red in f of regolator .
Now who is right ?
I have only 3 wire for old regolator. Yellow. Gredn / red. White /black ( comes from alt)
As i do not have the pigtail on rdgulator i dont know where to put these wire .

Alessandro,
I know your not converting to a tach, but look at the diagrams in figure 1. There is a difference in how the wires connect to the voltage regulator depending on the use of an Ammeter or a charge indicator light. The diagram comes from the Ford Shop Manual for 67, I haven't found it for a 66. Hope it helps.

Thanks anyway , but yes i have changed the ammeter into volt meter and i will add the rally pack with tacho
now is very messy ! And when wire colors dont correspond .... this is a challenge .
Thanks

Get yourself a 1965 mustang charging system wiring diagram. As for the pigtail to connect the regulator Napa sells a replacement.

The look a like "regulator" is used by PA Performance to keep the factory ampmeter.
You no longer need it.
Wire it up like the diagram that Steve69 posted.

Thanks !
I realized that i bought this regulator for nothing , because i got now a new volt meter ....
After study , video , info and and diagram i have found which colors need to be connected .
The video refers to orange ( mustang 66 is white ) field
The other one refers to black ( mustang 66 is black /yellow ) batt on alternator..
Now i will connect wires and check all is in the right spot .
Thanks all
Ps. I found different wiring colors from different service books for the same users . Beware !

thanks for help a dummie ! yep

'The alternator needs the resistance of a charge indicator light to "excite" the alt to start charging.
If you look at the diagram that Steve69 posted, you will see a 560 ohm resistor wired inline with the green/red ignition wire.
This simulates the resistance of a light bulb.
The diagram also shows a system with a charge light as well .... like a 65. It also has a resistor wired around light bulb .... this is so that it will continue to charge if the light bulb burns out.
