cant smoke the skins...problem??

RPM,
The chrome box wires differently as the ballast resistor should have the blue and yellow stripe wire on one side and 12V+ to the other, but it should be switched 12V (keyed) then the black and yellow wire shouldn't be hooked to a ballast resistor and should go to the coil - . See most stock igns. have the black and yellow wire going through the ballast resistor so to keep the stock coil from burning up due to the load that the coil would take, this is why they tell you to use a high output coil and resistor with the chrome and gold boxes. The ballast resistor is the rev limiter on a chrysler product, different resistors have different ohm ratings and the stock 4 prong has .5 ohms on one side and the other is 5. ohms on the other side. So you need to have a ohm meter to know where the wires have to be hooked or this could be your problem, having too much resistance on the ign. side and too little on the run side. This is why they tell you to use the correct ballast resistors with the right box and coil. The mopar boxes are as good as any when properly installed and they will out last most competitors and for the price and the performance they are hard to beat.
