1. Remove the affected exterior rear view mirror. Refer to Workshop Manual (WSM), Section 501-09.
2. Remove the original 16-pin door harness mirror connector. To remove the connector, follow the wiring
repair kit instructions included with the pigtail kit (Figure 1) and cut the wires 13 mm (1/2 inch) from the
connector and splice to the 8-pin gray and 8-pin black female connector pigtails.
(1). To gain enough access to perform the splices, pull the harness connector through the wire harness
grommet hole below the access hole for the mirror bolts.
(2). Using a small flat head screwdriver, remove the white christmas tree body-to-connector retainer
from the original connector and install it on the replacement gray female connector.
(3). Tape the female connectors together using electrical or foam tape.
