Got a problem. I couldn't get the connector off my MAP sensor and actually broke both the sensor and 2 of the three wires that go into the 4 pin connector. I've ordered a new sensor and connector, but I can't find the information on which location the 2 broken wires go to. The three wire colors are green and black, orange and black and orange. The wiring diagrams I have access to says those wires should be green and brown, white and brown and grey. I suspect the solid color orange wire is the signal wire. Also, the diagram shows those wires going to pins 1, 2 and 3. On my connector, pin 3 isn't used, only 1, 2 and 4. I'm hoping someone can tell me which wire, by color, goes to pin 1 and pin 2. I currently have a 50/50 chance of getting it correct, but really don't want to risk frying my ECU if I get it wrong. Does anyone have a photo of that connector with the wires in it? That would be very helpful. Thanx!

 

It would help if you put in your signature exact model and year of the car you're working on!
For x350 NA MY 2004 the correct wiring is:

OY=Orange+yellow
BK=Black+Pink
BG=Black+Green

 

If you were anywhere near me, I’d kiss you!
