Stevieturbo Posted February 6, 2011 Report Share Posted February 6, 2011 LEM G3. Wiring diagram lists both 2 pins at the rightmost of the connector as ground. It makes no differentiation as to which is sensor ground, and which is power ground. Yet the instructions in the manual clearly tell you to keep them separate. Which is which ?

Cameron Moore Posted February 7, 2011 Report Share Posted February 7, 2011 Hi Stevie, They are both power grounds and should be run separately to the block. Sensors should be grounded back to the base of these black wires near the ECU. Page 18 in the manual shows this well. Hope that helps. -Cameron Quote Link to comment Share on other sites More sharing options...
Stevieturbo Posted February 7, 2011 Author Report Share Posted February 7, 2011 Thanks, I see it now. Although it does list one as sensor and the other power without noting which pin is which. But yes, I didnt look to see that they both grounded together at the block. So the distinction isnt important Most other ecu's Ive wired always have a totally separate pin for sensor grounds. Not externally combined with power grounds. Every little bit moves one step closer Cheers Stevie Quote Link to comment Share on other sites More sharing options...
