Picture1 - Bad pic, this is the business end of a network cable. It has 4 pair of color coded wires for the 0-5v input to EFILive. I put a male blade connector on each solid wire which is POSITIVE, then a female on each striped wire which is negative.
Picture2 - This is a voltage divider circuit that we need to use to drop 12v down to 0-5v when using a variable resistor like the Summit Pressure Sender. The internet is a wonderful thing.
Picture3 - This is the network cable plugged into EFILive.
Picture4 - Top to bottom: Negative "medusa" ground wire to put ground to 4 sensors at one shot. Positive medusa to feed 12v to each sensor. A SPA sensor attachment, and it's brother.
