CIS-E engine wiring harness removal

Is cutting required?  I have everything out except for one bundle that
goes back into the firewall near the fuse/relay panel area and there
appear to be no plugs in between.  I really don't want to cut until I
know that's what I have to do.

Also, what is the electronic thing that is right next to the knock
sensor control unit (I'm not talking about the ECU)?
