is ther anyone out there that has a gn with F.A.S.T. that is using precisions interface harnes?i think my map sensor is geting power from the wrong wire. the instructions say to splice it in to the green wire and the green wire is hot at the plug but now my stock boost gage is peged out on the dash with the key on . i checked my friends gn and map plug is hot on one of the outside wires marked "c" on the plug. i must have something wrong somewhere but iv checked it over and im sure its done like in the instructions. any info would be great. thanks.
