Yep. I've printed it out and compared, but I don't know what the codes mean or anything. It's a huge mess. All I figured out is that the distributor vacuum is incorrectly routed.

 

Codes ?

You mean these ?

 

Yes, I have that printed out as well. I highlighted the acronyms whenever I found a match. But when I take the papers to the engine bay, it's like I just got dumped with a thousand piece jigsaw puzzle.

Maybe I printed out the wrong diagram??

There are still more codes that that list didn't include like MAN VAC, DUAL DV. I figured MAN VAC would be manifold vacuum, correct?

 

Correct

and

Dual DV is Dual Differential vacuum .

Now, Have you see the big Orange Hose routing Illustration?

 

Dual Differential Vacuum. Got it.

There are two in your gallery, which both doesn't apply to me. They are '77 and different options, I need '79 4x2, C6, no A/C.

 

...or not?
