Hi, I'm hoping to do the led rear light swap to my e60 530d. I've seen the Bruce Miranda cables available, still seems to be a few sets knocking about, but am a bit deterred by the price. I have seen a few people on here talking about making their own up. My friend and I make circuit boards and small electronic modules for music applications, so I'm sure we can build up a set of these. Does anyone know what the Bruce cables entail or what their function actually is or even have a schematic? Or even a link to another thread with this information as I can find none.

Many thanks for any help guys

 

It is because there is none.
