Procedure:
1. Connect the connection cable to the outside temperature sensor (see the manual from
manufacturer). Trim the unneeded insulated conductors up to the cable shield and note down
the conductor colors.
2. For connection to the Cluster Controller using two-conductor connection technology, perform
the following steps:
• On the five-pole plug, unlock conductor entry 1 using a screwdriver and insert the
insulated conductor of the wire into the conductor entry.
• On the five-pole plug, unlock conductor entries 3 and 4 using a screwdriver and insert the
insulated conductors of the connection cable into the conductor entries. Observe the pin
assignment.
• At terminal X7 in pin row A, place a bridge between pin 2 and pin 3 and between pin 4
and pin 5.
