Good lorrrrrrrrrd...never EVER again will i attempt to fix a vehicle with a wiring harness issue. I'll just set it on fire and send it down the road. After a lot of wrestling, the old harness is out.
I can't get over how freaking long this harness is.
Now i get to run the new to me harness everywhere, and attempt to put everything back in where it came from. before i put the dash back on, i'll definitely be doing a test fire to make sure everything still works. And i found my issue in the harness, i never would have found it without removing everything so this task was not for nothing.
This is the wires to the downstream oxygen sensor, notice how crispy these look? something was shorting out somewhere, causing my car to run in open loop all the time.
I also found out why my cruise control stopped working randomly about 10 years ago - I bet that black wire is supposed to be in that plug...
So i'm not sure if the hard part of this job is over, or if i'm just getting into it. Fingers crossed everything goes back exactly how it should and i have no bolts or pieces leftover lol.
