i put the sensor in the test pipe i built. it is installed, the wiring harness is run to the guage. now i have 4 wires. blue, white, red, black. i am supposed to be able to run it only as a monitoring device, so i dont have to splice into my stock o2s. so i should only have to put the red wire on the 12v switched source, and the black on a ground. but i got nothing. not working. any ideas? :fm:
