Re wiring details, the wiring was pretty straight forward with most of the time required to remove/reinstall trim pieces to run 1 wire from the inner left tail light along the side of the vehicle to the front passenger footwell, where the BDC_BODY is located.

You will need:

1) 1 X .35mm dia. wire (I used 20 AWG) approximately 20 feet long
2) 2 x connector pins (61138369696) or repair wires
3) 1 X Euro light switch with rear fog button (61319461141 or 61319461142)

Wiring Details:

1) Remove the the trunk lid liner - https://www.newtis.info/tisv2/a/en/g...ter/1VncxwUczG

2) Assemble 1 of the connector pins to one-end of the .35 mm dia. wire and insert pin into position 6 of the inner tail light connector. Note the connector has a pin locking mechanism that must be released (flipped-up) before the pin can be fully inserted.

3) Route the wire from the rear inner tail light to the BDC_BODY, following the OEM wiring harness in the trunk lid and along the right side of the vehicle:

i) Behind the right-side trunk panel - https://www.newtis.info/tisv2/a/en/g...als/1Vne3omLMM

ii) Under the rear and front right-side door sill covers to the BDC_BODY in the front passenger footwell:

- https://www.newtis.info/tisv2/a/en/g...les/1VndrMi9O6

4) Measure the length of wire to the BDC_BODY connector (be generous) and cut-off any excess. Assemble the 2nd connector pin onto the wire-end. Insert the pin into the appropriate BDC_BODY connector/pin location. For my vehicle, the fog wire was inserted into pin 20 of connector A258*5B - https://www.newtis.info/tisv2/a/en/g...hts/1VnchjSa6D

5) Replace NA with Euro light switch. I did not follow the instructions provided since I was having difficulty unclipping the side panel - https://www.newtis.info/tisv2/a/en/g...sor/1Vndt4O7on. I was afraid I was going to break a clip or the panel itself. Instead, I removed the storage compartment below the light switch - https://www.newtis.info/tisv2/a/en/g...les/1Vne2HKUCV to access the spring clips on the back-side of the light switch.

6) FDL Code BDC_BODY --> CAFD 7083--> LCE_BEL_LIN_VAR --> 30_BEL_PL_FLC_NSL (rear fog only) or 34_BEL_PL_FLC_NSW_NSL (font and rear fogs). This coding is not essential since the switch will operate properly. ISTA+ will just report a BDC_BODY error until coded.
