Can use some help on this. Recently purchased a RX2 and the brake,turn signal nor hazards are working. Fuse checked out ok, regular lights work ok, just no brake, turn or flasher operation. I am thinking it is a relay problem since all 3 functions aren't working. While tracing wires under the driver side of the dash where the relays are located, I noticed a 3 wire connector in the attached pic hanging out by itself. Can Anyone tell me if it should be connected to a relay and which one? Am I over looking something simple?

 

not to hijack this tread but im also having the same issue with my Rx2 no brake, turn or hazard....

 

If you can't even get brakes to work, something isn't connected. If it's anything like my REPU, there's a large relay under the dash that the brake and turn signals feed into. It works in conjunction with a flasher relay in the CCU. If you get brake lights, but turn signals just turn on and stay on, you may need to replace the flasher relay with a modern unit that works with LED bulbs. That way it won't be as sensitive to bulb resistances.
