Are you wanting a 100% stock setup? I think you had a TCS solenoid and it went here and there and back again OR are you looking for where the vac. to the dist. originates for just a street setup?I can post a pic of a 69 with a basic setup if you want.

The '71 SB, auto engine has a TCS solenoid mounted on the front-left side of the carb. It has two ports which route manifold vacuum through it. Vacuum can connects to the front port; rear port is connected to carb vacuum port. Sorry, I don't have a pic.

BBY,
Dr. Rebuild's catalogue has some very good drawings showing the vacuum advance lines. In 71 there was a piece of steel in the vacuum line between the distributor and the CEC Solenoid. Rubber out of the advance can, hard line, rubber into the CEC nipple.
Regards,
Alan

since the TCS was nothing but an emissions control item, and a pretty bad one at that, you could completely remove it and simply hook the vac adv can up to a full manifold vacuum source.

Thanks Guys for all of the info, yes it is a stock set up, thought it was wrong. The hose does go to the tcs when I went to disconect it to set the timing there was no vaccum, maybe the hose is on the wrong port, I'll have to check?

I leave my TCS stuff on the car, but bypass it for normal running. You can just pull the vacuum can line off the TCS solenoid and run it to a manifold vacuum connection on the carb; then plug off the open solenoid fitting. It works just fine and you can quickly get the engine configuration back to 'original' for a show, whenever you need.
