I have the sensor in and its wired correctly as far as i can tell. I test the sensor for a pulse and it pulses BUT when i hook the signal wire up to the gauge, the signal does not pulsate. The wire that comes down from the gauge is a yellow/red and connects to b16 on the obd0 ecu. If i have the wire going just to the ecu it pulsates. From what i have been reading it should just work. The only thing that i really have different is i have my power and grounds comming off of the ecu.

any help asap would be greatly appreciated!
