Fully refurbished to MINT condition MAIN & REAR HARNESS for Mercedes W113 230SL LHD, AUTOMATIC transmission.

1. Upgraded to RUN with Bosch AL69X Alternator.  This will enable you to run additional electrical accessories up to 80A.  Also this kind of generator has internal regulation, so it will be more reliable, and is a model that can be sourced in many places, therefore is cheaper.
2. Upgraded COLD START Logic.  This harness has been modified, so that it runs on the 280SL cold start logic which requires two standard 4 prong relays instead of one standard relay and a timed relay (later one difficult to source).  This will improve dramatically your COLD and HOT engine startups.
3. Totally New T30 and T50 lines.
4. All Cable ends and Connector Labeled.  To make your life easier during the installation
5. TTS, Thermo Time Switch Terminals upgraded. So that you can use a modern TTS from a W116/126 which has internal solid state components, much more robust and easier to source.  If you want to keep using your original TTS which has different cable terminals, and adapter has been provided.
