So clean dude... how do you like that ethanol sensor? How was the install?
Thanks.
The most difficult part is getting the wires through the firewall. Easiest thing to do is remove the knee airbag, and disconnect the sensors (6) and connectors (2) under the dash and footwell, respectively. There’s one ground and two or three zip tie fasteners that secure it to the firewall. From there, you can pull the main harness grommet out of it’s groove and into the engine bay; be gentle, because the idea is to pull it out just enough to get the wires through. Pulling on the grommet alone will be difficult since everything is secured and there’s little slack.
It would probably take about 45 min with the right tools.
Personally, I went full stupid with drill and hit six wires. But, my Air Force career was in communications electronics so I was able to fix my mistake. I had to pull the harness completely out of the passenger compartment and ended up running my wire through the sound symposer tube.
Unfortunately, the wires are not quite stuff enough to make it around the bends if you want to try to through the sound symposer tube.
