Good morning! So this is my first post in the forum, so forgive my ignorance. I recently obtained an LS3 engine and 6L80e tranny out of a 2017 Chevrolet SS for my 1959 Impala. I have the engine installed in the vehicle but as I am trying to get it running, I am running into connections and ports I am not familiar with. Specifically, the port located on the front passenger side pictured below. I bought a harness from PSI and had then reprogram my TCM and ECM but do not see a connector for this port. It appears to connect to the throttle body some how but is not used. (I am currently on travel so I do not have immediate access to the engine). As it appears to not be needed, how do I plug the ports where it is connected? what is it called?





Thank you.!
