Hey,
According to NHRA rules, can a battery disconnect switch be located anywhere outside the car behind the license plate??...(just wondering before i go drilling the hole)!...thanx

As long as you don't have the license plate covering it. Run the track with the plate off. Then remount the plate with some standoffs, to clear the switch, for a nice clean look on the street.
Use the Moroso plan for the alternator wiring and you risk a fire.
The 10 gauge wire they recommend is even less adequate that
the stock Mustang wiring.
There is a solution, but it will require about 40' of 18 gauge green wire.
Wire the battery to the two 1/4" posts as shown in the diagram.
The alternator requires a different approach. On the small alternator plug
there is a green wire. On the diagram it is #904, lt green/red wire that connects
to the alternator and dash light. It is the sense lead that turns the regulator on
when the ignition switch is in the run position. Cut the green wire and solder the
40' of green wire between the two pieces. Use some heat shrink to cover the
splices. See http://fordfuelinjection.com/?p=7 for some excellent
help on soldering & using heat shrink tubing.
Run the green wire back to the Moroso switch and cut off the excess wire.
Try to run the green wire inside the car and protect it from getting cut or
chaffed. Crimp a 18 gauge ring terminal (red is 18 gauge color code for the crimp
on terminals) on each wire. Bolt one ring terminal to each of the 3/16" studs.
Do not add the jumper between the 1/4" stud and the 3/16" stud as shown it the
Moroso diagram.
How it works:
The green/red wire is the ignition on sense feed to the regulator. It supplies
power to the regulator when the ignition switch is in the run position. Turn
the Moroso switch to off, and the sense voltage goes away, the voltage
regulator shuts off and the alternator quits making power.
