How to Install Switchback Turn Signals

Due to so many incomplete threads relating to this and no video on YouTube that i could find, I've made this for those who want to do this mod. It's a very great visual enhancement and looks sharp. If you have an 08+ balt, your wiring should be the same as mine (2010), if not, get your multimeter out, and get ready to poke around ;)

You'll need:
10mm Socket
trim removal tool or a flat head screw driver (tabs on front bumper/grill)
multimeter
wire strippers
electric tape
type 2 switchback led's w/ 6ohm resistors (this stops hyper flashing)
your cobalt

Step one:
Take your headlight assembly out. There will be two screws per headlight as well as a tab on the black bit that is your grill, its the tab closest to the headlight. Once you get the assembly out, unplug your turn signals and remove the old bulb (save them incase these leds ever go out). Then grab your multimeter and start poking for a 12v DC source of power from the four or five wires coming out the turn signal harness. Mine was the top blue wire (power) and black at the bottom (ground). Now what i did was cut the two wires in the middle, not to split them, but to expose the wire under the rubber insulation and also to aid in the crimps contact.

1. This is the crimp, the resistor will not go through the whole way, it will only go in one end. And the harness wire will go straight through, the crimp will act as a jacket.
2. These are the power and ground wires you want to tap into.



Step Two:
Once you get them plugged in and you think the wiring is all gravy. Start testing with each turn signal that your lights are working properly, turn off your auto lights (if applicable) throw on the hazards, test left right. If everything is working, great then tape up your crimps.

Step Three:
You're going to want to put the resistors somewhere where they wont melt things, I hung mine so that they don't touch anything. These resistors get very very hot, so avoid plastic as best you can. While I was testing mine I didn't realize they get as hot as they did and burnt my finger a bit.





See? I just kinda hung mine as such. DON'T MELT YOUR PLASTIC

Step Four:
Enjoy your new found automotive gainz




They look great and for $10 bucks it's a great mod. I AM NOT RESPONSIBLE if you screw up something or pop a fuse. If anyone has questions, ask away. thanks!! Mods if there is another thread similar, kill this.

No no, thanks for the heads up, I edited it. I am quite jelly haha I'm in texas, I believe flashing blue and white is illegal, at least if my memory serves me right!

Mine have the chrome look when off but flash amber when lit.

You do realize they have LED switchback that are plug and play? Pull the factory bulb out, install switchback. I have 60's. Almost bright enough to be use as headlights
