EMS220 Pin 2 (yellow wire) is it connected?

[jmurtagh13]

I think I only have one yellow wire coming out EMS 37 plug which I connected to my backup 12v Battery. So configuring the SV the widget reads 0. So if indeed there is only one yellow wire it's likely pin 12 (Input 8). I'm just confirming this is the case and I would need to take the connector apart and install the missing pin 2 wire?

Thank you

If you can see a socket in pin 2 then it's there, I'd use a DMM to check anyway, also check your EMS Sensor Input Mapping see page 7-64 Rev V of the Install Manual.

If the harness was bought within the last few years there isn't a wire on pin 2 (the same harness is the primary harness on first generation EMS products, and on that product it's keep alive, and we no longer recommend that one use that wire, so we unpinned the harness that's common to all of the first generation EMS products and SkyView's EMS modules) The best way to check what that wire is connected to is to do a continuity test from the wire to the pin. Likely, it's going to pin 14, which is the fuel flow signal pin. It shouldn't be connected to a power source.

Thank you for your reply.  So the yellow wire you're speaking of is part of a bundle that goes to the red cube and that's working fine.  The stand-alone yellow that I thought was pin2 must go to pin 12 (input 8), so yeah that also should not be connected to 12 volts. 

So now my question is can I move that yellow wire from pin 12 to pin 2,  so that I can take advantage of the second volt meter built into the EMS?   I have an EMS220 that I bought about a year ago.

If it's not being used for anything else, you can.

Added a new wire to pin 2 yesterday, connected it to my backup battery works great.
