Default Factory LS harness?
Hello,
I didn't know if this should go in the electrical or EFI section...

I plan on dropping in a 5.3LS motor in my 70 shortbed pickup, but I have a question about the factory harness:

I was wondering why I need to have the factory harness modified? Why cant I just use it the way it is? I will delete vats and other stuff in the ecu that I don't need.

Any help would be appreciated.

David
