I posted in the general tech area but hopefully will have more luck here. I have a customer that has a 1958 190SL and would like to put a 2003 3.2 and automatic from a CLK320 in it. I am looking for someone that can take the harness and computer and make it a stand alone. Any suggestions would be appreciated.
Thanks, Jon

The harness you have already is stand alone. You just need to figure out what things you can leave disconnected and what has to remain in place.

I went down that road in this thread.

I understand basically every car can be made stand alone. I have never worked on a Mercedes before so I am not familiar with what is where. If someone already does this they could do it a lot faster than I could. Like building staging, sure we can do it but why when I can buy it for a fraction of the cost.

Why are you stuck on getting an aftermarket harness ( that does not exist ) ? Use the factory harness and modify from there.

As I stated in your other thread, use all of the wiring and make the engine / trans think it is still in the CLK, this is what Roncallo did with a SL600 V12 in a much older SL body.

Option one is to make it work with factory ecu and harness, cause you need to get gearbox also work. Biggest/most annoying issue is i to get abs signals and you need a star to code out some unnecessary extras.

Second option is standalone but then you need controller for gearbox. If you go for standalone then start cutting factory harness or chose a guy whos nearest to you and does that stuff. At beginning you have definitely some issues and that way its fastest way to solve then.

For that car i would go option one to get that "like from factory" feel.

I never mentioned an aftermarket harness (other than putting a Holley in like my own car) All I am looking for is someone who has already done this. I have wired blown pro mods with all kinds of lean outs, shock controllers, converter bleeds, EFI multiple stage nitrous cars with sensors for anything and everything. I have never worked on one of these cars before, I could figure it out but if someone has already done it I would rather pay them. (like we did on the 2015 Duramax project) It would get done a lot quicker and (hopefully) done right the first time.

Yes I have done it. But not on a 2003 3.2. Each one of these is going to be its own unique situation and if there was a person who did this for a 2003 3.2, its probably only applicable for 1 to 3 model years of that combination. You will be on your own with this one.

The good news is it really wasn't hard once you figure out how to defeat DAS. I figured it out for the 96 SL600 but that was a non-transponder system. You will need to figure out how to do it on the newer transponder type systems, which may be easy, possibly just tape the key fob to the transponder sensor and stuff it permanently under the dash.

Feel free to give me a call on this. I can guide you through your options. It depends on what you want to do and what you want as far as systems from the newer car. It can be done from full aftermarket to full factory. Or somewhere in between.
