Planning to make a more detailed video by the weekend! Yes, the wireless add on is just a module that sits near the JB4 unit under the hood. The OBDII connection is recommended either way@Ben_21TPP
For the kindness of your heart you can video a step by step of which plug to remove from what.where and plug it on which plug of the JB4 it would be great of a few of us dummies when it comes to this skill. One more thing you really need that wire from the bay going to the the OBD port even if you purchase the wireless add on? Looking forward to your tutorial video. Thanks in advance.
