CSi CABLING CONNECTION QUESTION

Dropping 3 volts with 0.9 ohms means a current of 3.3 Amps, which means the resistor is dissipating 9.8 watts, so I’d use a 20 watt resistor. Check Digikey or Mouser
You can still buy ballast resistors, the original was 0.9 ohms.

@HB Chris and @ScottAndrews Friends, what an amazing explanation — yes it is a BMW 3.0 CSi VIN 4341353 was manufactured on October 23rd, 1975 and delivered on December 1st, I’m learning so much from you all! That wire is completely burned, so I’ll have to replace it. Do you know where I can find a proper replacement? It really is transparent almost yellowish transparent. And another question: should it then be about one meter in length? Thanks!!!
My CSI is a phase 2 with that resistance wire etc, however yours is about 1,400 units sooner on the serial number than mine. Mine was built in Dec 1973, road registered in 1975 due to extreme U.K. prices for these cars.
How did you determine your build date, mine came from BMW with a certificate so I am reasonably confident in it. However, mine is RHD and I assume that yours is LHD, perhaps BMW ran two serial number sequences for R vs L HD?
 
I’m back in USA on 9th- I will check for a wire for you at Shop
