re rout your o2 harness. another header melt down.
you need a new o2 sensor too, that things form the factory.
rockauto will likely be the cheapest place to find a o2 sensor. add a code at check out makes shipping free. or advance auto on line and local pick up if your on a time crunch.
i cut the o2 plug off my cars harness, and added 3 foot of wire to it. ran the wire down the strut tower to the rack then right to the o2, nothing hot in the way.
oh, get a delco o2 sensor too.




That was two weeks ago; got a love tap from a hottie in an Audi. She said she bent down to get something from the door pocket and bam! LOLThought someone rear ended you at first.
Heck when I did my rear driver side wheel bearing I just took out the whole E-Brake assembly. Didn't work anyways LOLThe other day the e-brake decided to start turning off the "auto-on" lights when the e-brake is applied; it hasn't done that for about 4 years. Interesting. LOL
Right through that gromet that harness is running throughSo I need some help, trying to run a power wire through the firewall, but the hole everyone is saying to use has tubing behind it facing down and it's full of water?

Where am I supposed to run this damn 4 gauge wire?
