I am in the process of converting the car in my signature to obd2 (thanks to fieroflyer for the awesome harness). I had a few friends help with the conversion and we have a few connectors remaining we cannot find where they go. One of them is the map sensor plug. I cannot find the map sensor can anyone help. Thanks in advance and sorry if this already exists out there but I could not find it.

I should add that the car used to be obd1. And that the car runs great now on obd2 already even without the map sensensor being hooked up but it is throwing a code for map sensor low voltage.

Just plug a GM MAP sensor in and you can zip tie the sensor in place and use a section of Vacuum hose and a "T" fitting to connect it to manifold vacuum. I used the fuel pressure regulator vacuum line for mine.

2 Bar Weatherpack MAP sensor

You can also look it up as the MAP sensor for your donor engine.

The connector will be either White or Orange on your harness. The MAP sensor stock location is between the rear valve cover and the supercharger. Alternative locations are by the fuel pressure regulator or on the transmission. The MAP sensor MUST be connected to the lower intake manifold port. That is the port located below the supercharger snout. That vacuum/boost source should also be connected to the fuel pressure regulator and the BBV if retained. Nothing else should connect to the lower intake manifold vacuum/boost port.
