Re: NOT so EZ wiring

You cannot use the blue wire to the wiper switch. It is the power wire (OEM yellow wire)
from the fuse panel to the wiper motor. The wiper switch is grounding only for the two speed motor. All the wires that go to it are for the grounding side of the wiper motor. This includes the wire for the washer motor. You have to be careful wiring the bl/yellow to the motor. The diagram from the factory is wrong. It shows the yellow wire joined with the black wire in the factory diagram.

You will need to use the fuel pump wire in the LS harness for the fuel pump on your engine. The OEM did not have a fuel pump in the tank. You probably know this, but others reading your post might not.
