Volvo

I am working on a Volvo that had the wiring harness destroyed by 
rodents.  I would like to get it running again to use it as my daily 
driver.  Unfortunately, I have no idea which wire is which.  The car 
is a Volvo 240 with the 2.3 litre and LH-Jetronic.  As far as I can 
tell, the computer is the 2.2 model because the throttle body has 
the throttle switches.  Also, if anybody has any idea what resistors 
to change and what that change does, the information would be 
helpful.
