The injector plugs at the end of the harness go to which set of injectors? Primary or Secondary? I just want to be sure.. Thanks..

 

Your question doesn't make sense. The front injector plugs are on one brach of the harness, the rears on another. The plugs should basically fall onto the correct injectors. If you have any difficulty getting a plug to reach an injector, it's the wrong one.

 

Oh ok. I thought the set at the end of the harness go to the primary injectors
