Impala/Caprice Installation Page 7
Here's one side finished, notice the new wiring harness taped to the factory harness at several locations. Reinstall the tail light assembly back into the car (besure to install the center bulb). The left and right turn signals are wired identically except for step 24, repeat steps 23 and 24 on the otherside.
Locate the factory tail light wiring harness inside the trunk, free it from its attaching point under the trunk lip.
You can leave this factory connector together, or seperate it as shown. Remove some of the electrical tape and cut the yellow and dark green wires approximately 2 inches from the connector (besure you are cutting wires on the tail light side of the connector).
Attach the yellow wire (from the factory connector) to the white wire on the left signal plug (blue dot on connector indicates left, red dot for right) on the new tail light wiring harness. Notice the tight mechanical connection of these two wires prior to soldering, these can also be crimped or wire nutted. Attach the dark green wire (from the factory connector) to the white wire on the right signal plug (red dot) on the new tail light wiring harness.
