Does anybody have a pic or schematic showing what color tracer hoses hook up to what vacuum pod for the ac control unit?

I'm away from home until Saturday. If you don't get a response beforehand, I can send you pics from my 70 unit when I get get back.  The tracers are still visible.

Zero - it looks like headejm has you covered with the pictures.   If you need something else, post a message.

I think you'll find that the routing of the lines around the box the curve that has set in the shape of the line will get you close.

One thing not mentioned, there's supposed to be an extension harness, those vacuum lines will get you just about to the top of the steering column....  If you have the extension harness great use it, otherwise they have gotten hard to come by so I would expect to splice in about one foot of vacuum line to each line....

Here is a sketch of the plug. The orientation of the vacuum motors is when facing the box looking at the firewall side, as it sits in the car. The top most motor has two vacuum lines.
