Default Under Dash Vacuum Lines - 1969

I'm a big old guy and with size 14 feet I must have knocked these vacuum lines loose somehow. I've looked at the diagrams on Willcox but can't find them.

I only want to go down under there once, cause I may not be able to come back!

So before I contort, I was hoping you could tell me where the double end goes, and also the single tube.

And no, I haven't tried any switches to figure out what is not working, I'll still need to know exactly where they go

And if there's anything I can do to stop them coming off again.

Thanks

The double connector should go to the wiper door override switch I think the right hand side of the wiper over ride switch, the single line if proably the one that connected to the "tach solenoid" which is bolted to the rear of the tach.

I agree with Mooser. You can try to use some zip ties to bind them to something higher.
