Yea, I know that you get it. The sue happy people tend not to see when a shop / person genuinely helps someone out.

I'm also guessing that you are going to be torn between your own time commitments and the desire to keep helping the car owner. This is something that the sue happy also don't see.

Changing the engine harness is an hour / hour and a half job. All the wires lay where they are supposed to be making the job easier. The throttle body connector might be difficult to get to from what I recall.
