Hi, I'm about to connect the rear PDCs retrofit. The question is, can I take the CAN and CAN hi cables from any side where the cables of that color are visible? Or is it necessary to be from the fuse box harness? The harness that goes to the back of my E90 has both cables of the same color. Is that possible?

The cable has to be identical or similar, is that ok? Solid or braided like the original?

Can bus is exactly that, a digital communications bus shared by all connected devices.

It doesn’t matter where in the bus a new device is plugged in (excepting termination but that is a separate issue).

So yes it does not matter which side the device is plugged into.

I found the Can bus to be very sensitive to resistance loads and even solder impedance changes, so make sure you use identical wire and have very secure and good connections. Don’t accidentally cross connect the high and low sides anywhere too.

Thank you very much, I bought the same cable but only a different color, I will try to install it over the weekend

Thanks

If you absolutely MUST use different color cables use a wire label on both ends of each cable to identify it.

Your future self or buyer will thank you for that.

Thank you very much, it works perfectly. I already have parking sensors. Thank you.
