Can someone confirm that for wideband I can take the -5v reference and Signal ground and 12v all from the options connector pigtails?


Or is it better to tie into the harness.

If I need to get the -5v reference from harness , which symbol indicates -5v?


Thanks

 

I used pins D and A for the analog signal from the gauge (white and brown wires) to the options port on the MS3 but powered the gauge direct from the fuse box.

 

Thank you. So the D for white analog is the O2 input? I don't need to use +0-5v?

 

Is this the 30-0300 ?

White to D, brown to A. 12v to the fuse box and I ran the ground out to the engine block. It's laid out in the gauge manual. All the other wires are for datalogging, etc.

 

So you did not use data logging into MS?

 

Yes - AEM 30-0300

 

The other wires are for the optional AEM data logger. You can still use Tunerstudio to data log.
