Goes to your PEDES valve if you still have emissions equipment.

Re: Any idea what these are
Do you know if they can be traced back and removed with some negative effect? As the valve has been removed (never existed while I have owned the car) the wires just hang in the engine compartment. I haven't been able to find a pic of the EGR valve on a TBI 305 or the wiring diagram.
