I have looked everywhere, I have just swapped an engine from an 87 K-5 Blazer to an 84 4x4 Truck. I have all the Vacuum stuff connected as the Diagram on the K-5 showed. There is one connection though that they dont show and that is the port on the manifold- I have seen other post of people asking this question but know one seems to have the answer, I know you have your vacuum line from your resevoir that comes over and your cruise control and your HVAC line that comes over but know one shows a diagram of how that system is supposed to be hooked up together, There is a check valve as well.. Any Information would be greatly appreciated, Thanks.
