I am using only three of the seven wires coming from the LC-1 unit to tie into the FS. The colors are Yellow (Analog 1), White (System ground), and Green (Analog ground). I have both the White and Green tied together.

The Yellow (Analog 1) is connected to the E pin of the external pinout and the other two (White/Green) are connected to pin D.

The black and Red a tied to switched 12 volt power respectively.

I also set up the Log programming software under Anolog 1 to the following settings

.883 volts at 9.99:1
4.216 volts at 19.99:1

I then selected the program button.

I also selected the appropriate PID for {EXT.AD1}

Is the wiring correct? I keep reading about the ground issues and want to confirm this is wired correctly.

Thanks

Howard
