The wiring harness has been care fully labeled in all its terminals.  It is included a main fuse box, to reduce installation time and to avoid errors.

Wiring Harness rebuilt service Mercedes W113/111/112/109/108/114/115

Dear friends

I am dedicated to my hobby with Mercedes Benz and it’s electrical systems.

Anyone interested in rebuilding his own wiring harness to keep originality or because lack of new options for his particular car, contact me. I will help you in all the process.

Base rate for a main harness rebuilt service USD 1,000.

Particularly interesting are those cars for which is impossible to source a new harnesses as: w108/109/111 and 112 coupes or sedans.  Plenty of experience on those.

Also can manage more complex cars as w111-3.5 and similar motorized cars.

Modifications to main harness to accommodate newer technologies or options that came on later Mercedes cars are also feasible. Examples:

1. Adding a hazard relay sub wiring harness. Eliminating original flasher
2. Modifying charge system to use more modern internally regulated alternators like Bosch AL66X, and increasing charge capacity
3. Modifying Ignition circuitry to use later original Mercedes transistorized ignition, which still uses ignition points, as a triggering device instead as a high current passing through element, increasing therefore lifetime expectancy by 400% and keeping the original look and distributor.
4. TTS override circuitry
5. Electrical wiper pump managed from the foot mechanical pump.
6. Low brake fluid circuitry
7. Buzzer system when lights are left on and ignition is off

And creativity is the limit.

For those not worried about originality can embebed alarm systems into the original wiring harness and make it unnoticeable.

Dear friends

Attached some pictures of another perfect job that I just completed.

Enjoy, and think, the electrical system on your car has never been rejuvenated, nothing last forever.

This work was for a customer in Chile who is doing a wonderful job on his w108-280SE. Main, secondary and A/C wiring harnesses have been rebuilt up to the minimum detail.

Best regards

Leonardo,
I am in the process of restoring my 1970 280SL and will want to either restore or replace my harness.  My harness looks good, but in my experience with restoring Corvettes, it is better to replace the old harness with a new one.  I've seen a few Corvettes burn up due to old harnesses.  What is it you do to restore harnesses and how much would it cost me to have my old harness restored?  Is your restored harness ready to go for installation upon receipt?  My car has an auto trans and is LHD.  Thanks for any information you can provide.
Sincerely,
Mark Spencer

Recent Air conditioner wiring harness custom made
« Reply #6 on: July 20, 2021, 21:11:24 »
Dear friends

See attached pictures from a recent sub wiring harness I made from scratch for a customer in SINGAPURE who had an aftermarket a/c system on his w108 RHD but wanted a professional approach for it now that he is restoring the car.

The logic is this:
1. 1x main power relay taking energy directly form post T30 at the battery
2. 1x change over relay cutting power to main relay when engine is being cranked
3. 1x relay controlling the condenser electrical fan
4. Electrical condenser fan is triggered by radiator water temperature reaching the desired level via an adjustable thermocouple and also triggered by refrigerant pressure reaching a predefined threshold
5. Compressor protected against refrigerant gas escape cutting it off if that happens
6. Auxiliary fuse box for the system.

Best regards

New w121 Ponton wiring harness available ebay
« Reply #10 on: July 25, 2021, 12:09:00 »
Dear friends

I found on eBay a new wiring harness for a Mercedes Ponton. If anyone wants to give his cars that chance of having a new electrical system here is the link.

The harness comes without connectors and accesories.  It requires work to be operational, work that I can do that with pleasure for you at a reasonable cost.  Just PM to study and quote your particular case.

Best regards
Leonardo Peterssen

How do charging loom cables look after 50 years

Dear friends

For those who think that the wiring harness of your cars is a robust one, and believe everything is fine because It works, see attached photos to realize what is happening there under thick layers of tape or electrical tubing.

What happens is the second rule of thermodynamics (if I remember correctly from school): within a certain frame of reference entropy increases with time. :)

Thank you for sharing!
