Im currently doing a full boosted build for a customers 96 GSR. Were running a Walbro 400lph pump, and i am doing the fuel pump re wire mod to insure proper voltage to the pump. I need to know which wire is the positive wire to the pump on the harness that plugs into the top of the sending unit, and i cant find the info or a tech article anywhere. Im assuming its the yellow wire with a green stripe, because its thicker, and the other wire is black with a white stripe (assuming thats the ground), but i dont want to start cutting and soldering until im 100% certain. Id check with a volt meter but im currently finishing a wire tuck and the battery cable isnt routed yet to hook up to a battery. If someone could just confirm this with me real quick it would be much appreciated. Thank you, all.
