Yanking PCM/Harness ?'s inside

Pulling the harness for the DFI install.. Are there any particular wire's i need to keep? i'm just concerned mostly about the headlight's.. the module that control's them is that ran off of anything other than 12V on? and foglight's as well? any pointers? not really concerned w/ the Speedo/tach or any dash gauge for that matter.

you can remove the engine harness alone by locating te harness on the passenger side firewall. there are 4 plugs under the carpet that will enable the entire engine harness to come,and leave the power harness intact on the drivers side.
