these are hard to find. I have an 03 escape V6 and this diagram helped me to debug a wiring issue with the o2 sensors. The schematic was accurate for my purposes - so I think its good for an 03 escape.

I've taken the eight images and spliced them together into one jpg. I think its a little easier to follow the wires across pages. You can download the image then pan and zoom the single image much easier to trace wires. See attached.

There is a lot of confusion as to bank 1 and bank 2. Bank 1 is cyls 1,3,5 and are the closest to the firewall. In the diagram the comments on the O2 sensors are misleading at best (or simply wrong). H2OS 11 & 12 say "(right side of engine)" - these are bank 1 and are the closest to the firewall. H2OS 21 & 22 say "(left rear side of engine)" - again this is wrong - it is bank 2 which is closest to the front of the vehicle.

Hey,

Great addition to this thread! Please feel free to help out on the site whenever it can add information that will help. I have updated the engine wiring diagrams in the above

Best, Ken

Thanks for this post! I am unable to read the combined jpg before or after printing. Initial reply has 7 of 8 pages of wiring diagram. If top Left is #1 & bottom right is #8... #4 page is missing. Thanks in advance.

Sorry, I have updated the engine wiring diagrams in the above post let me know if you need anything else. Cheers, Ken

Hi I have a Escape 2004 v6 4wd 3,0l , same pinout pcm connector ( 104 pin )...In this tread you have posted here with 8 picture , is this diagram for 2wd is aplicable to my escape 2004 4wd ? Or we have to find a new one specialy aplicable for the 2004 version ... I need more explanation on this aspect about those diagram please?

Concerning my case , i have taking the first step to begin to check the '' Ground Wire '' of the motor and pcm , to be sure of all good connection . My truck have been shooted with oil since the beginning , but some loose or broken wire can induce some intermittent problem with misfire in accelaration ... Something shure presently i have some intermittent noise pickup over the air on weak radio station on the AM band . I have all ready change the antenna kit . same result ... When the truck was newer no noise was present...
Thank you

Hello.

I had a look at the 2004 Ford Escape diagrams, they are identical to the ones listed above.
Also, there is no differentiation between 4wd and 2wd.

You should be able to use these wiring diagrams.

Regarding your radio issue.
