Can someone post a pic of "T" in line from cruise servo to decel valve?

I'm trying to resurrect the cruise control in my '82 SC. I've walked my way through the troubleshooting table in the Bentley manual and it passes the tests except the first one (the voltmeter reads infinity between ground and pin 3 regardless of whether the clutch is in our out, but I've pulled and tested the clutch switch itself and it is fine).

I had pulled the engine out of the car about five years ago to squelch some oil leaks, and it is quite possible that I didn't hook the vacuum lines up correctly, so I read extensively on this board and learned that the small line from the cruise servo is supposed to be connected to the line from the throttle body to the deceleration valve with a "T" fitting. I looked on the car, and found that:

--There is no small line connected to the servo; only the big vent line
--The line coming out of the center of the deceleration valve goes to the left side of the engine compartment but is plugged with a golf tee.

My recollection is that the cruise control worked when I bought it, but I'm 52 and I forget stuff.

Can someone post a pic of this T-fitting on a late 'SC, and of where the line hooks into the throttle body?

Thanks.

nevermind, figured it out

Using a mirror I looked at the front (facing the front of the car) side of the engine and saw where the short hose connects to the throttle body and tees to the decel valve and the cruise control servo. All the vacuum lines appear correct. I'll check the servo by putting 12v and a vacuum on it, and if it works and the cruise still doesn't, I'll chalk it up to a bad brain.
