Hego sense:
Dark Green/Dark Blue Obviously Ground is ground. Heating is: Black/Dark Green (-) Grey/Yellow (+)

ok I have hooked it up to the Green/Blue and nothing just reads at the bottom of the Gauge...... same with all 3 wires and I have put a new O2 sensor in just to see if it was that but made no difference.

have you killed what your attaching it too?
Im sure feeding it 12V at a large quantity of current wouldn't do it well.

it would be best hook the signal wire to the input at the ecu...
that way your not risking shorting wires by trial and error.. i know with the el ecu its pin 29.. but unfortunatly i dont know about the ef ecu.. |

also when you first start the car the guage dont move for the first few mins untill the exhaust gas is warm enough to give a true signal.
well mine dont move for the first few mins anyway.. |

really??? I like your idea about going to the ECU and it's pin 35. I might have to hook it up and take it for a drive.
