1) What is the "ALDA"? Where is located? What does it look like?
2) What is the "IP"? Where is it located? What does it look like?
3) What is the switchover valve? Where is it located? What does it look like?
Thanks again and sorry for the basic questions.

It is the square-ish looking unit on top of the IP (question 2)
2) What is the "IP"? Where is it located? What does it look like?
Stands for "Injection Pump" The aluminum bodied unit on the left side of the engine with five metal tubes, one going to each of the five injectors.
3) What is the switchover valve? Where is it located? What does it look like?
I think they mean the overboost protection valve. It is a little solenoid with 2 clear plastic tubes: one coming from the back of the intake manifold, the other going to the ALDA. Both are connected with "banjo" fittings (you will eventually ask what a banjo bolt/fitting is). The banjo bolt on the manifold side (12mm wrench) gets clogged with carbon, and will not give a proper boost signal to the ALDA. The overboost protection valve may be clogged, or inoperative as well (preventing boost signal).
