We at WCCC have been assembling used headlight vacuum hose kits, and while we were at it, we laid them out on the ground to take pictures, and I went ahead and made diagrams to show all the components / colors / routing / etc. There are already factory diagrams readily available (we have them as free downloads) but this is a different way to visualize it. I’m posting these new diagrams here as a resource for the benefit of the Cougar faithful. Hope these are useful!
Clicking on any of the pics will take you to the download page where you can get a high resolution PDF version for free.
