Note:
Ensure socket contact is seated securely.
3.5.4 Insert socket contact of line RD/GN 0.35sq into chamber 2 (30G) and additional micro-quad lock into chamber 3.
3.6 Only for vehicles with micro-quad lock connectors as of model year 08:
3.6.1 Press socket contact of line RD/GN 0.35sq out of chamber 4 (30G I) => Figure 10 -A-.
3.6.2 Crimp micro-quad lock (999.652.901.22) => Figure 11 -A- at one end of the additional electric line 0.35sq.
ATTENTION:
Do not connect additional electric line as a splice to terminal 30G II, chamber 2!
^ Roof console Wake-up function does not work!
=> Connect garage door opener to terminal 30G I, chamber 4.
3.6 3 Connect the other end of the additional electric line 0.35sq as a splice => Figure 11 -B- to the electric line RD/GN 0.35sq from chamber 4 (30G I).
Note:
Ensure socket contact is seated securely.
