Brake tail light strip on trunk is out. trouble shoot ? bulb on right side tail light is out. but can't find data on tail light strip of lights on trunk
Lets simply thing here. American Auto Manufacture use three wires set for it
rear light assembly. One wire to the braking switch for both stop lights, one
wire for the clearance light on both sides. Now if you look at the plug for
taillight assemble there will three wires and didn't mention the third wire,
it's ground. The two brake light uses one wire, then for on or clearance light
uses one wire, and the ground uses one wire On old automobile normal the grounds
any place on the body. But now the grounding points to make sure there isn't a
faulty ground.
Turn signal light are a separate circuit as with the back up lights. I fairly
sure your Caddy uses a Mylar strip with copper strips on it. Find were this
copper strips are broken, scratch off the thin layer insulation and solder a
jumper wire across the broken copper strip.
There will be a Central location where these light are tied together. Left
brake light wire goes to the one wire from the brake switch under the dash, the
right brake light goes to the same tied point to brake light switch under the
dash. The Central wire point will be at one of the back lights. Just follow the
colored wire. Now, each has two colors, one solid and one strip is colored with
different colors. I hope this help you. GB stewbison
