I am down to the last bit of wiring on my carbureted 6.0 L96 all seem to be straight forward except the ECT wiring. Im running auto meter gauges but not 100% sure where to connect my sensing wire from the gauge. Do I need to tap into the MSD harness or am I missing something in the wiring diagram?

 

Are you trying to use the same sensor for to outputs (ECM & Gauge)? I'm not sure but if it will work using a factory sensor. The factory sensor using A for ground in the ecm and B as the sensor signal wire.

 

I am trying to use the same sensor but not sure if I can or not. Maybe I need another sensor for the gauge?

 

I would. You might start getting a different resistance and they won't be accurate. Since the heads are the same, you could just put another sensor on the opposite head in the same spot.
