i have a si wire harness which plugs up.but the plug by the drive side next to the brain box doesnt fit my dx plug. the si pluge is smaller and it has 8 wire and my dx has 12 wire. i want to cut my dx plug and rewire it t my si but i dont know how to do it. my dx plug is too big so can anyone help me???

 

what year are you talking?? it should work fine for a 92-95, your si will have more wires for v-tech, and i believe a dx isn't wired up for v-tech. I don't konw, i ahve a si harness in my cx right now, running a 98 dx motor, and mine works fine.
