Even though there was no mention of it in the instructions I had to dremel the plenum to make room for the connector for Injector 1.
Since I was more comfortable dremeling with the plenum off I had to reverse a lot of my progress. I searched and didn't see anyone else mention this so I am posting this for reference.
