Title: MAP sensor wiring
Post by: larrym on May 29 2018, 01:02:50 PM

So I wired my power logger to the green wire terminal A on C437 like I had it in the white car and nothing, the connector is not connected to anything and I have ran power to terminal F to run the motor, there is no power at the map sensor and I have probed the C437 connector terminal G black and white marked as ground has 5 volts? Nothing at terminal B I jumped the G and B together and got a reading of 20 PSI on the powerlogger? Is it as simple as grounding terminal G?

I'm not sure exactly what you are asking but this is one way to hook a map sensor to PL.     http://www.vortexbuicks-etc.com/PowerLogger.htm (http://www.vortexbuicks-etc.com/PowerLogger.htm)

^It's also a much better way.
