Need help rewiring a Mercedes wiring harness Sign In

Hi guys, I hope you can answer some questions or at least point me in the right direction. I recently purchased an 1995 Mercedes-Benz C220, well the wiring harness wire insulation is falling off of the entire thing due to something that plagued all of them of that period. I want to rewire the entire engine harness and need some understanding of how I determine the wire size. Also some of the connections I believe are a coax on the hall effect switches, does anyone know how to repair/replace the coax going to them?

"Making" a harness is not really an option. Your only choice is to get you hands on another replacement harness somehow, whether it be used or new.

Well I have my old wiring harness, I'm just going to re-run all of the wires on it and replace the broken pin bushing housings as they all have part numbers. link deleted ... not allowed shows them repairing/rewiring the harness.

OK, then why are you asking us then?

Good luck with that.

Well being that this is an automotive wiring forum I thought I might run into someone that knew a little more info about rewiring the coax lines.

We do know a lot about them. We know that they cannot be spliced or made. You can send your harness out to be rebuilt by a professional but even that is a questionable repair

I can tell you for certain that this would not be a DIY job, and to do it right would take some rather expensive tools. The problem with older luxury cars is they cost a fortune to repair. I'm a tech and I wouldn't want a 95 Mercedes if the guy gave me the thing.

Not my cars and not the point. Never tooled up for them.


No matter it's a old carmaker and proud of itself at least someone is. High bet Benzo itself still sells an entire harness for just what you want at a price that would make anyone choke. If you love it/them it's fine with me but if you have to ask how much to do what it's the wrong car for you,

Therein lies the problem. I like Benz cars. Who wouldn't they are very fun to drive. They are very intricately built. Thats why they cost so much. Problem is, they cost more than a regular car to buy and they cost more than a regular car to repair. Thats why not all of us are rolling around in them and they are a status symbol.

I drive a Bronco, and I like working on them. You could call me a Bronco enthusaist easily. But I also have an income that allows me to keep up with the maintenance and repairs of a used Bronco. While I would love a Benz, I do not have an income that allows me to afford to keep one in running order. The high cost of parts and repair is the biggest reason why older ones can be had so cheap. You aren't getting a deal, you're buying someone else's money pit that they couldn't afford to repair. Why do you think rich people sell off an $80,000 car thats only 5 years old? Its not like it was worn out or looked bad, its because it was worth dirt and was needing a lot of money in repairs and it was easier to just buy a new one.

A Benz is not a DIY project. A Benz is not a car that you can afford to own even used without at minimum a $150,000 per year income, more depending on what area of the country you live in.

My uncle in Tampa, FL is a physical therapist that has found a niche practice with higher-end clientele. He drives Mercedes cars exclusively. He doesn't keep them any longer than 5 or 6 years before they get traded off for a new one. While he does pretty well financially, he would keep the car longer but he said the cost of repair after that point isn't worth it.

If you don't have the kind of money it takes to keep this running and are tying to find a cheap way to repair it, this car brand is not one you should own and it is why myself and the rest of us on this site also don't own them. We are by no means in poverty, we are professionals in our trade, but that isn't enough income to support a vehicle of this type.
