So lately I have been working on a project. I am working with an OEM 2005 Cobalt SS/SC wiring harness. I'm using lights from another vehicle. The other vehicle lights have a bulb setup where one bulb is for running light and brake light, the other bulb is turn signal alone.

I haven't been able to figure out how to isolate the turn signal from the Cobalt harness to that one bulb. I've even tried tapping into the front turn signal harness with no luck. I am working with the Cobalt harness Yellow wire (Left/haz/brake), Green wire (Right turn/haz/brake), Brown (running light power), and Black (Ground). The other vehicle has a four wire setup, Dark Green (Right turn), Light Green (Left turn), Red/Black (Running lights), and Black (Ground).

I think I have tried just about every combination and I'm lost...

Any help would be greatly appreciated!!

Oh and I've got the running lights to work using the Brown wire and used the wire from the third brake light to illuminate the brake light. I just can't get the turn signal to work when it's separated.

Well I forgot to hookup the power wire that branches off the battery cable, DOH! Working with a cut up harness so it's difficult to determine what needs to be hooked up to each circuit.

Tapping into the front turn signals is the what worked for me. Used the center brake light supply voltage for the brakes, and normal supply voltage for the running lights.
