Side Terminal, Internal Regulator, External Fan Alternator
This unit was optional on 1987, standard on all 1988-92 models and standard on 1993-96 models equipped with the 4.9L and 7.5L engines. The regulator in integrated within the alternator body and is not adjustable.

 ============

Voltage regulator is either external or internal.

Internal inside the alternator,you will have to disassemble alternator.

If voltage regulator is external then,it is bolted on the back of hte alternator.

For more information the parts store had the regulator: for $9.79 (as opposed to $177 for the alternator).

One more thing , when unplugging the regulator plug on the back of  alternator to check the configuration before buying the regulator, that there's a fair bit of corrosion in the contacts. So plug/unplug it a couple of times, and check. I've put 300km on the truck and the voltage only spiked twice. (and that's with the contacts not properly cleaned, just disturbed a bit by plugging/unplugging).

It is "behind the passenger side battery". The starter solenoid on the fender.This is what the external ones look like, and normally it is near the starter relay on the P/S inner fender:

See the image below for ford 85 inner fender:

The lower left corner of that yellow circle (box?) goes right over it.

Opening an alternator isn't that hard and doesn't require any special tools. Only difficulty can be the brushes when reassembling.
