GM Maf Wiring

[wird06DSM]

Well my V3 for my 2g will be ordered her tomorrow. So today I wanted to straight wire my gm maf to my factory harness. I have a gm maf plug and was wondering if anyone had a wiring diagram to remove the factory maf plug and straight wire the gm maf plug to the harness for the v3 setup?

Details: The GM MAF cable is actually a little more than just a cable. It incorporates a small PCB built with high quality surface mount components to provide signal conditioning required to feed the GM MAF signal to the ECU. In addition, the cable provides break-out connections for both the IAT and baro inputs to the ECU. The Baro input is run through a buffer circuit so that you can freely connect any 5v sensor to this input without fear of overloading the sensor.

You can see the small PCB in the picture:

You might not want to try and wire the GM MAF directly and use the cable they sell.

Yeah, the cable is awesome. You should order it.
