So what is the part # to that wiring bypass and who makes it!
Take the plug apart and remove the 4 clipped wires. Open the small retainer that holds the covered wire in position. Unsolder / break the wire from the pins. I could not successfully open the wire retainer - so I broke the strands of wire. I took the new wire - stripped the end and soldered it over the closed exposed wire, and then closed the wire retainer over the new wire. I did this to all 4 wires. I used 4 different colors - red / green / yellow / black.
This is the part that I should have taken pictures of - the exact connections that all 4 new wires attach and / or replace. But all 4 wires are joined by the air cleaner box - to the various junctions. I put these 4 wires in their own harness.
The front O2 sensor will go first, then later the back O2 sensor will trigger the engine on light. The second O2 sensor can be fixed later - if you wish, as it does not affect the engine's performance - like the front one.
I should have completed a step by step procedure for this project - but time was getting short.
Again - I gotta run!
1. Are all four wires near the air intake filter or throttle body?
2. Are the colors the same in tracing as by the M/F adaptor
3.reconnection is no problem just need to know where?
Thanks
My wife took her Durango today to Cranberry Fest, so I can not give you the rest of the wires / location. I beleive the wires are the same color throughout (Durango side connection).
In aid of research - I went to Alldata and paid the fee to research the factory manual. I still ended up ripping out the wire harness from the back of the engine to the end of the transmission - to insure I had the right wires. This is where I should have documented my actions.
I know I am leaving you hanging - but I would have to have her Durango here to rip the tape back off - to give you the correct answers.
But I did not use this Jumper. I just cut off the ground wire which causes the problem and ran a new ground to a different location. See my other post about this. Good luck
Question for DURANGOFAN: There are alot of wires coming out of the harness at the PCM.
1.Are they ALL located in the same connector or do they split off into different harnesses at the point of the PCM. 2.If I stand on the right side of the vehicle (passenger door on my left side) and look down at the air intake there are 3 plugs into the PCM and one plug underneath those 3
Which plug are they located in
This one is to ARAY: It seems like all four wires are producing PS Fluid but you said it is the ground.
Question?
1. Where does the ground lead back to, the PS switch?
2. I like your idea of one wire to reground too, but, do I ground it to the chassis or back the (NEG) battery or pick up a common somewhere else. I have to say that it seems like a huge amount of fluid to be coming out of one wire, is this really the culprit?
Next Blog and its a GO!
The black ground wire is a ground for the power steering switch plus the O2 sensors. If you are just going to run a ground wire - the factory connection is on the inner fender skirt on the passenger side. Take the air box off and you will see several ground wires connected to a stud / nut. A ground is a ground - as you can connect the new ground wire to any where a ground wire can be established.
My weekend is full of 'house chores', so I am not going to dig into the wiring harness to identify where the wires go today.
Try and replace just the ground wire and see if this cures your problem. On mine - I replaced all 4 wires at once.
I'm sorry - but super busy.
please let us know!

I don't get it. When I put the new 02 sensors in a week ago it ran great...now it is back to it's old self... I even took them out and cleaned them up during this bypass...got any ideas?
Should I do an entire bypass
Should I get another 02 sensor assuming the new one has shorted out?
THanks in advance,
Jason
At the moment the durango is running well. I did rewire the ground only which is not "black with a blue stripe" it is a "black" wire only before the connector (alot of fluid dripped out of that wire). After I ran a new ground there was no change...so I rechecked computer and the o2 sensor was coming up "lean" therefor more gas was called for by the PCM....problem was back AGAIN...son-of-a-@#$%! Before I cut all the wires in frustration..I considered a brand new o2 sensor to replace the other brand new o2sensor...another 85.00 shot-in-the-dark. I thought that in the shorting out of the first new o2 sensor it might have mad it so-called "lazy" I reattached all the original wiring and put a wire connector in to allow the remaining fluid in the ground to drain through that splice without it going into the M/F connector.
Bingo...it works...for now.
The key to this whole thing for those of you who might read and have the same problem was that the PS sensor switch is the culprit! A 30.00 part that is so easily replace and can cause on heck of an issue...REPALCE that switch first and go from there.
Thanks for all the imput from ARAY and DURANGOFAN, a big help to bounce stuff off of
At the end of August I left to study in Sweden. I have a friend who starts my vehicle once a week and will drive it 10 miles or so every couple weeks. She recently told me that the check engine light has returned.
I am just curious how likely is it that I am having all of these problems at once? I service my vehicle regularly (3,500 mi) and I do not abuse it at all. The fluids are often checked and I hardly drive over the speed limit. There are no leaks and after the trouble began I started using high grade gas, whether that helps or not. I have spent over $1500 dollars within a very short time and would like to know if others have experienced such problems or perhaps my mechanic is toying with something. It has seemed that be has been unreliable with meeting deadlines and keeping contact.
I would check the heater core and connection for leaks or internal rust, if it hasn't already been checked.
Could someone list the step-by-step process? Correcting this doesnt seems difficult. So far: problem is 3 months old, Switch and harness is wet, poor gas milages, check light on dash, pending emissions test next month. Help & Thank You Board Members :sick:
I just got my car back from the body shop because a tree and power lines feel on it. Does anyone know if the electrical wires could have caused this? I'm trying to get this covered under insurance since I've already paid $1000 for my deductible and JUST paid the car off.
Transmission just failed.
