[DML] Re: Engine Grounds

["Dave Swingle" <swingle@xxxxxxxxxxx>]

They ground all the sensors and switches on the engine. At least those 
that need grounding, i.e. most of the ones with two wires on them.

The ground wire with the red jacket on theback side of the passenger 
side intake runner grounds the ECU - i.e. the frequency valve computer 
that is run by the O2 sensor. 
 
So - yeah the engine might run with all that stuff disconnected but it 
may not be happy about it. 

Did you check the interior ground at the bulkhead - BOTH inside and 
outsideand to the frame below the water bottle? That causes about the 
strangest stuff on the car.
