This is a 4 pin Molex to Molex connector that is used to connect innovate products directly to the Adaptronic ecu. We also use this cable to interface with the AEM product line but it does require you to cut off one end of the cable and connect only the white wire from the 3846 cable to the blue wire on the AEM wideband. A great combination to purchase with this cable for AEM customer would be in our section which includes 2 pin connector kits so that you can disconnect/reconnect the AEM wideband to the serial cable.
