You need to slit the rubber grommet under the brake booster.
Ive removed trim around centre console and can just feed it straight through to other side. Is the rubber grommet piercing necessary (cant really see it) or should i be ok to just push the cable through?

The grommet is there, just to the right of where the wiring loom meets the bulkhead. Pull the black foam out of the way and you’ll see a rubber cone. Poke it through with a screw driver and feed a long cable tie through with the obd cable taped to the end.

This worked! Thanks. Took a while mind you but got there in the end :)

So I got the o2 sensor code. Now I do have a downpipe...but the reason I'm asking here is because it started happening with the JB4. I ran the DP with the Neuspeed module for about 900 miles with no CEL. The JB4 went for about 200 miles...then the CEL came on. I cleared it...then within about 70 ish miles...the CEL came back. The DP I have is a Wagner Tuning. The cat is in the stock location...and so is the bung for the o2 sensor. Is this something related to the JB4?

I wanted to add that coincidentally...it came on after the intercooler install.

Bank 1 is the first o2...the one with the black sleeve? That's the wire I tapped for the AFR wire.
