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.

Guys, I installed my JB4 with the Bluetooth, the only thing I'm suffering with is finding a place to route my OBD cable through the firewall.

Man this firewall has no good access on either passenger or driver sides!!

I saw two large grommets on both sides but I can't locate them on the engine bay side.

In the spirit of helping others: Maybe someone could make a video of install (just the part where going from driver to engine compartment) or video of grommet location? I’m crap with video making myself

I care, but no videos....

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.

It’s hard lol. I was breaking my back with a flashlight to find it. I needed help or never would of found the bung.

More bad news. Another CEL came on.

report back if you do get codes for the cat, i'm just curious if the little mini cat spacer works or not. i can just disable in the tune. But just curious if it works.

still no cel, but do show a code in the JB4

Make me think I'll do the 200 call DP to avoid the CEL

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)
