Hey i purchased this kit used and was looking at the wastegate and was a little confused how to hook it up. I know i need to hook up a vac line to it but the previous owner hooked up the line on the side instead of the vac spot on the top, or at least that is how it appears to me. Do i need to get a fitting and have a vac line run from the top too? Im lost at what to do. Oh and the top vac hole isnt plugged currently, it is open to the air.
