Be careful, I have read somewhere that if you supply 12v to the Blue/Yellow wire it will harm the BCM. That wire is designed as a ground activation for the BCM to alternately flash the reverse and brake/turn signal lights. I am away from my reference materials.

Hey, FH,
Go to the New Caprice home page and look under files. Find the 2013 General Motors Caprice only technical manual. Page 22 has a better description and the warning regarding the 12v to the BCM.

Big thanks to Steve and Maurice! Anyhow I found the missing link. When I added the horn/siren wire to the switch, the high beams alternate now as well. That was the issue. Both flash no problem. Separator wire is cut and decommissioned.

Hi
Have same problem with my 2012. All lights and horn work. High beams dont flash when I give 12v to the green/red wire, only the rears flash. Where is the "separator wire"? I checked the diagrams posted and I dont have any black wires. What am I missing?
I apreciate any help.
