I want to by-pass the stock electronic control unit that connects to the stock distributor on my '84 Dodge Caravan.

I see that the mopar's 'orange box' or ignition control module is used with ignition systems in later motors.  I've look at the wiring diagrams and I'm trying to figure out how it would hook up:

The 2.2 distributor uses the following wire colors:

orange

grey

black / light blue

---------------------------

The wire colors of the mopar orange box show the following:

green/red (or blue/yellow)  --- to ballast resistor and indirectly, to positive + on ign. coil.

black/yellow  --- to neg - on the ign. coil

green/red --- not used

grey/black --- to distributor
brown/white --- to distributor
------------------------------------

So my question is, which wires from the original 2.2 distributor do I connect to the wires that the orange box will use?  I'm assuming the orange and grey wires are going to be used.  

I think your gonna have to go back in time, I think there was a 2.2 in the very early 80's that had a control box.
Do some research and see what you can find. You might be able to determine what yr. and then get a dist. and box from a wrecking yard if you can find one.
good luck  

I saw an interesting application for the mopar orange box:

The main advantage, as I understand it, it is to direct the current into the orange box and avoid burning out the points.  So I can hook it up to my 2.2 Caravan which by the way has a modified VW/Bosch 009 distributor.

BTW this ignition mod is documented here:
