Whats up guys.i have a 2009 997.2,and i just recently purchased a icarsoft por 1.0.i connected it to my obd port,and it did not power up.so first thing g I checked is the cigarette lighter fuse,all was good.so I got to playing around with the obd connection to my car,and all of a sudden it powered up,and I was able to use it to reset matinence light.so I tried connecting it again to see if it worked ,and it powered up 3 out of 5 times,again after wiggling the connection to my car. So long story short,I thinks it the connections in my cars obd port.i want to check the obd connection. Can anyone please tell me how to get the obd out from under the dash? Or do I have to take lower dash off,and if I do ,can anyone lead me in the right direction. Any help is much appreciated. Thanks
