Hey Guys

After some 29 years, I noticed that the insuation on the wirings have gone brittle and I am looking at changing them. Spefically I want to change the wiring the connects the "Plug terminal for engine diagnosis (12 52 1 273 100)" to the fuse box. I can only find the "engine wire harness (1251 1 274 655)" in the ETK. So my questions are:

1 is this the correct wire harness?
2 there is only ONE wire harness and it connects the just about every electrical socket in the E21?

Thanks, hopefully Elisabeth will back on the road next month........ :driving
