I bought this item and give it an initial 3 stars because it appears to be a very nice product. However I was greatly disappointed that there was no kind of instructions on how to connect the thing. For Christ sake it has five (50 wires). That in my view was very poor of the venders. No one wants to be stuck with a product they cant use which is were i am kind of at right now with this. Please can simple wiring instructions based on the colors of the pig tail be placed in the product discribsion.i.e which two color wires are the ones to connect to the shunt, and which is for voltage measurement.
