In order for the kit to work, there is one more thing to be done. The right door jumper harness must be changed. The right jumper has a three wire end and a four wire end. On the end with three wires, the blue wire is to be moved to the empty cavity of the connector. The mirrors will work with the corrected jumper installed.

Insert the right and left mirror motor jumper harnesses between the mirror motor pigtails and door harnesses. Be sure to use the correct part number for each door.

3. Fully seat mirror control switch into the escutcheon. Position the switch so the pigtail exits directly under the word" mirrors" on the escutcheon. Secure the switch into the escutcheon using the set screw.
