Sup everybody. I got a 92 si eg wit a fully built b20/vtec i have the old hondata piggy back system wit a p28 ecu. I dont know how or why but the wires from the ecu to the piggyback disconnected and there are 4 wires a beige/orange, red, grey, black. I dont know how to hook the wires in through the piggyback if some one knows how or has a diagram i would really appreciate your help.
