I took off my 3rd brake light the other day to see if it was compatible with the plug-in-play after market ones. It doesn't have just one wire to disconnect then re-connect to the new one. I have the stock 3rd break light in now. Any ideas on what to do to make it a easy plug in play for a new light?

 

You have to follow the wire back to the connector, from that you join your after market light.
