First pic is the diagnostic port for the ECU



Second is for the Cruise Control servo



Third I think has something to do with the HVAC system, but it could be for the ECU to read the air pressure to determine altitude.

The second pic is the plug for cruise control servo.

This is the altitude sensor for the ECU.

Don't remove anything from the engine/DME harness. Most everything else can go.

The altitude sensor is a binary switch. Over (dont quote me) 3500 ft it reduces the fuel load by 4%. It is wholly worthless in my experience and I have seen only a handful that still worked.

Yeah, it's just an open circuit under normal operation, so just pull the thing.
