changing wire harness on chasis volvo vnl

[ktbtrucking]

Hello,

something snapped yesterday under my truck and I have all wiring,air hoses and fuel hoses around my driveline.
Have removed it and figured so far that. fuel lines are cut at the end of transmission. At the end of the cab all wires attached to the frame are cut.( All wires and air hoses).so all is good at axles. No hoses at air dryer. Air tanks cables are all good.
It is 2006 volvo vnl.

Will have a quote from the repair shop tomorrow on the repair. Any suggetions on repair costs.
Assume need all new fuel lines. Reconnecting air hoses. Put new wiring under the cab and chassis probably.
Any thoughts? All is missing at the end of transmission to end of cab.
