Just unplug your Edge with attitude from the map sensor on the block, plug the male end of the juice into the female of the EDGE EZ then plug the male end of the EDGE EZ into your map sensor....clear as mud...
This will have your edge with attitude running through the Edge EZ into the map sensor....or you can reverse it to run the Edge EZ thru the juice then into the map sensor. Try it both ways see which way it runs better for you. Probabaly not the best stack in the world!!
