Wiring harness question
 

Ok so I have decided to reroute an hide all my wires in the engine bay! I have done pretty much everything but the two main connectors at each strut tower. Now my question is, do those connectors make one big loop? cause I am wondering if they do then I could use just one of them to go into the engine bay instead of both of them. Anyone that has wired a whole car may know. Thanks for any info!
