Yes I put a msd ready to run distributor I have a dual ballast resistor 1 side has a jumper in it from the factory it has a light tan with a large blue the jumper to this is I believe brown tan on the bottom and blue on top the other plug has 2 wires with no jumper in it 1 on top is green and the 1 on bottom is I believe brown I disabled the green because that went to the old 5 plug ecu do I now take the brown wire from the plug that had the green wire that I disabled and connect that to the bottom tan wire or the top blue wire of the plug that has the factory jumper wire
