blazer -
here\'s the early style sw - the later one has a slightly
different look , but the wires are the same - you may not have some wires, but the critical ones should be the same if you have the correct original color wires .... the different colored wires to the ign resistor are to opposite ends - the 2 green should go to the coil so it gets power either from the resistor or the starter bypass .... I think I got that right!
