Euro 500SEL / Can I remove the add on K-Jetronic?

[MJM]

Hello,

I'm not new to Mercedes but I am new to older Mercedes, especially Euro spec. I just purchased an '85 500SEL and had some issues that were because of a faulty warm up regulator.

I'm waiting for a new warm up regulator to arrive so I can get the car on the road again. While I've been waiting I have been cleaning things / investigating. To get the car federalized they added an O2 sensor and K-Jetronic. I found the K-Jetronic control box in the passenger foot well. What I'm trying to figure out is can I remove it from the car?

I am removing the cat and trying to get this car back to the way it was in Germany, removing any remains of US tampering.

Some other things they did under the hood with fuel / vacuum lines are a bit confusing to me. I figured I'd ask the question and see if someone has been through my situation.

Attached is a picture of the box I found.

Thank you for any input.
