How do I repair the Phays?

Hint 1 of 5:

First, you'll need to learn how this circuitry works.

Hint 2 of 5:

Try helping the woman in the Oratory.  When you do, you'll have that
knowledge (or at least Spock will).

Hint 3 of 5:

Next, you'll need a couple of parts from a somewhat obscure location.  Read
on for an answer if you don't already have what Spock needs.

Hint 4 of 5:

Talk to the king so that he leaves.  Then use the light switch just about
Jakesey's head.  "Get" the panel that drops down to take the lightbar and its
wiring.

Hint 5 of 5:

Now try using the lightbar on the wiring.  Klarr will offer to help you
remove the connectors that you need.
