The rear O2 sensors are different lengths for Euro vs US which means the DME harness is most likely different (definitely different part number):

Euro
Oxygen sensor BOSCH/L=750MM 1 11781405324
Oxygen sensor L=480MM 1 11787832035

US
Oxygen sensor BOSCH/L=1075MM 1 11781406621
Oxygen sensor BOSCH/L=935MM 1 11781406622

The US ones are longer, so you would think it would reach with some extra slack. The location of the O2 plugs might not be in an ideal spot to clip them in under the car with the euro cable box.

I put the Euro DME harness in my car a while back because I was unhappy with how my hacked US one turned out. Easy job. Three of the four sensors are on US cars but have to be rotated around, and I had to buy the 480mm one new (Bosch generic from eBay for $50). The harness used to be a couple hundred bucks which was a no brainer to me. Last I checked it was like $600 now which is pointless.

The engine harness is not long enough to reach the locations where the plugs should fit in the euro harness. The US O2 sensor harnesses themselves are longer than euro so you can make it reach without cutting, it just won’t fit into the factory euro clips perfectly.

This is where I am at ^^.

Thanks to all three of you guys.

Hello Heinz,

When you de-pinned and re-routed your post cat O2 harness was the wiring long enough to accommodate the OEM Euro wire guide/connector mount? My harness is not long enough to use the wire guide/mount, and I am trying to determine if I somehow did not fully extend the harness or if the shortage is to be expected.

Thanks.

Hmm, mine feels like it should be long enough, but I accidentally didn't buy all the necessary euro parts when I did it, so I didn't end up using them. My wires are currently just tucked into the transmission harness clips/zip tied out of the way.

I think Bry5on did it the same way I did and also installed the euro stuff? Not sure if he extended the wires though.
