Re: Tune Up

Does anyone have a PN for the o2 sensor harness? I can't find one. I just don't see how to check anything on this harness with it installed. Too f***in tight. I do see that the convoluted tubing they use as protection for the wiring is about gone. I wouldn't doubt there is a wire grounding out somewhere.

You wanna talk f***in tight? You are gonna have to come up with a whole new vocab to replace that harness. HOLY GOD! That spaghetti mess is one giant octopus! It's all interconnected between O2 Sensors, injectors, ECM and other "stuff". No separate wiring runs.

p/n 56044237AF (Wiring, Injector)------> Item 1 in pic below.
Retail $1,100, Street $775

And the kicker, can you imagine getting at all those clip brackets, etc...?

Holy crap you'll have to practically pull the motor out just to replace the wiring harness

Re: Tune Up

Ya, the word "harness" on these rolling computers equates to "oh $hit" these days.

Re: Tune Up

Jeez... I was hoping they had one just to replace the O2 sensor harness. Screw that. Any other ideas on how to fix a broken connector? I'll try the zip tie idea Sleeps mentioned. Not sure I can do it one handed.

Or you could buy an 02 extension and cut off one side and wire tap it in.

If it's at all like my '02 (WJ) Ltd 4.7L the harness end connector (I think your problem/broken one) is held onto a metal bracket via a plastic push thru rivet style snap. If same, I used long needle nose to work that connector off the bracket so I could get it an inch or two free play to allow me to, in my case, clean the contacts. Maybe once off that bracket you can zip tight and either re-install or zip the combo to the bracket.

Nope... it's wedged up between the bell housing & firewall half way up the side of the engine block. There is a plastic rivet... and a bracket... but the bracket is attached to the main wiring harness, not a hard point. So you push against it & it moves with you, flops around, or twists to the side.

Re: Tune Up

So I got the brilliant idea last night to remove the O2 sensor I just installed & put the old one back in to see if it gets rid of the code (no code prior to changing out the part..and this was the only side I didn't have to pull & mess with the harness to disconnect the connector due the clip being broken). If it doesn't throw a code, then I know I just got a bad one from RockAuto. If it does, then I know it's in the wiring.

I'll give it a go tonight when I get home from work. Thankfully, it's still in the 60's & 70's here.

Otherwise... if anyone has any other bright ideas... throw them in the pot.
