Years ago I saw how to wire ethernet to the back of a retrofited CIC. And of course now I can't find it. Does this have to go to the ODB or can the ethernet go directly into the CIC?

My ultimate goal is to flash the CIC using enet protocol in winkfp. If that is even possible, can I also flash the combox the same way? The rest of the E70 is current so I won't be flashing ever again.

I have the USB ethernet working for the glove box USB. I assume that can't be used for any flashing right?

Thanks

It's a simple harness to make to hook it up to the OBD port. Alternatively you can use some CAT5 cable and have it direct with Ethernet connector. Up to you.

As mine is a retrofit, I don't have etherenet wiring between my ODB port and the CIC.

I realise that. It's a very simple harness to make though. 5 wires if I recall.

Anyone know where the 5 pins need to go? Planning to wire mine up soon to script activate cic after my retrofit.

I don't think Ethernet is needed for script activation. I wired mine up and it is not capable of doing anything on a pre LCI retrofitted car.

I wouldn't sure if FSTool would work with just a DCan cable, parts of the guide says to use E-SYS or FSTool I assumed both needed a enet connection.

you can the ethernet go directly into the CIC

Anyone have the wiring diagram for this mod? especially the ETH_A pin that goes to OBD pin 8 and is shorted to Pin16 (+12V) using a 510-550ohm resistor

A little after the fact perhaps but here's the pinout:

ETH_TX+ (green/white) to OBD pin 12
ETH_TX- (green) to OBD pin 13
ETH_RX+ (orange/white) to OBD pin 3
ETH_RX- (orange) to OBD pin 11
Spec is for 510 ohm resistor between OBD Pin 16 and OBD Pin 8

FWIW 510 is not a standard 20% value (100,150,220,330,470,680); it's a 5% value which is not typically available locally. 470 works or you can put a couple in series to get closer to spec. Or just order the 510 from somewhere.

did you try to wiring cic using ethernet? succes?
