Hey guys

I have searched and trawled the manuals (I have a 1994 PDF) and found the CAS wires go to pins 4G, 4E, 4H. I have the 4E and 4H wires correctly labelled I just need to know if 4E is a ground or power for the sensors? I am using a Megasquirt ECU and have 2 wires for the 2 sensors but then I have the 2 remaining wires coming out from each CAS sensor that join up towards the ECU plug into 1 solid wire. I am unsure if that is a ground or power wire?

Cliff:

4G and 4E are both single wires that go to the NE and G sensors, then 4H has the two remaining wires from each CAS sensor join into one wire and go into 4H, what is the 4H wire for? Power or Ground?

Thank you
Ash
