OK, so I've read the existing cruise refit threads for Gen-1 Legacies, and the parts to grab are supposed to be:

 

Cruise computer (must match the transmission), dash switch, steering wheel switch, brake switch, and cruise motor with cables.

 

Most of these were easy. A little too easy. The donor victim was a '90/'91 Lego wagon that had been attacked for its wiring harness, so the dash was already out and in multiple little pieces... including the cruise computer just sitting right on the back seat floor.

 

The two that confused me a little were the Brake switch... is it this one?

 

 

And the other one was the "motor with cables". I had seen it described in another thread as being connected to the throttle as a 2nd cable, so I traced the 2 throttle cables to see where they went. One went to the firewall (obviously the one attached to the gas pedal), and the other went to a little black cylinder bolted to the driver's side firewall, that had a vac (?) line attached to the other side of it, which in turn attached to a hard line that went somewhere on the other side of the engine bay and down. Being as brilliant as I am, I forgot to take a picture of it. Is this the correct part? If not, can someone take a picture of the correct part (preferably installed, for reference)?

Yup, you need that cable, the vacuum actuator, the steel vacuum line that goes across the firewall, and the vacuum pump it attaches to on the other side.

 

You need the clutch switch too if it's a manual.

It's not a manual.

 

Was that the correct "brake switch?"

 

And I guess I will have to go back for the steel line and vac pump.
