Dear Friends:
Selling price USD 1,350 OBO + shipping
I just finished during these lockdown times this wiring harness . It came from an early style MB 230SL Manual transmission. It has all the bakelite with screw type connectors. Most of them are perfect, except two from the headlights which have a cracked bakelite cover which can be seen on the pictures posted here or in the iCloud link below.
This harness has been fully inspected, all the original insulation material has been eliminated to visually check conductors integrity. All the charging system related cables have been replaced for new ones, marine grade, full copper, made in USA.
Charging capacity has dramatically increased from the original 4 mm2 cross section we have on this harness a 10mm2 section which will allow to install alternators up to 53+37=90 Amps capacity. Up to 37A can be consumed on the original fuse box instead of 28A as per original design, and up to 53A can be drawn via an aux fuse box directly from battery. So, to handle an Air conditioner system for this harness will be a piece of cake.
Starter solenoid cable has also been replaced for a new one toe to toe, I mean from Ignition tumbler directly to starter solenoid. This is a common problematic cable in all the wiring harness I have serviced so far, and responsible for erratic starter behaviour and energy losses.
All the works done on the charging and starting system will guarantee a very low discharge rate on the car battery since there are no cables with compromised insulation which generate parasite currents during operation and on standby. Also there is no risk of catching a fire, or at least it is minimised since all conductors are in great shape, and proper size fuses have been installed as well.
This harness is prepared to use a modern style alternator with internal voltage regulation. No external voltage regulator is needed, and therefore another source of problem in the charging system is eliminated.
All contacts on each individual bakelite connector have been carefully cleaned and polished in order to have a predictable behaviour on all electrical systems.
Main fuse box terminals are also shining and perfectly clean.
The cold start system has been revised in detail and new conductors installed all trough.
You have only to install your main light switch, ignition tumbler, and high/low beam foot switch in order to use this harness on your loved car.
This wiring harness is not for a purist, but for a practical driver who wants to have fun on his/her car without unexpected behaviours derived from a poor condition electrical system. Do not assume that your current wiring harness is in great shape. That is impossible after 50 years of being born. Not any of the wiring harness I have serviced for customers, so far, proved to be in perfect condition after removing all the tubing insulation. All of them had problems related with the charging system, or the starter. The material used on those particular cables does not resist 50 years.
More than 20 professional hours have been dedicated to this wiring harness to bring it to the pristine condition it is right now.
Also forget to mention that H4 headlight connectors need to be installed on this harness as I ran out of stock, and have no possibility to get a set for it nowadays. (do not worry you can take that part from your old wiring harness.)
