What is the difference in all the ECU wiring harnesses for an e24? I show bmw made a whole list of part numbers and wanting to know what all is interchangeable.
There's a lot of similarities in the BMW harnesses as long as they're the same revision of fuel system. Carb/Jetronic/Motronic. Most of the differences are for different locations of components. For instance, I have an E34 535i harness in my E24. I had to lengthen a few cables to the AFM and it's a bit tight at the DME. Most of the connectors were designed by Bosch and didn't change much over the E24 production run.
Save the manuals!
