    Found one, the rubber grommet is terrible to route this big cable through, I found a lnother small plastic that I poked and it was super easy, look at the photo.

    Got the CEL again. Looks like the spacer is not working.

    Just get a flashlight in there and you will see it, it is a smaller opening than I expected. Just look for the little cut-out.

    So I had my JB4 connected and I wanted to see if I have and pending codes. It said it was unable to connect to ecu? I closed app and tried again still nothing. I know it’s connected because all the readings are showing afr etc. Any ideas?

    When you rev your engine does the rpm on the JB4 app go up?

    Yes everything works I just wanted to see if I had a pending CEL for DP but it wouldnt read or connect to ecu. I had the car idling in park with the Jb4 on map 3. Is there a trick or reading clearing codes?

    No trick at all. I just click on read code and then it pulls all the codes.

    You do need to make sure the car is in diagnostic mode to clear the codes though. (Hit start button 3 times fast)
