I found a speaker wire tapped into a blue wire of the Hazard SW Harness. It feds to one led on the Brake SW. While one of the Y on Blk Break SW wires dangled and the other was connected to the Break SW led.

I've tried the following combinations and I can not get the break lights to work:

1) Spk wire from Harzard Harness and one Y on Blk wire = make the rely click every 5 seconds but no brake lights

2) Spk wire from Harzard Harness and the onther Y on Blk wire = no break lights

3) Both Y on Blk wires to the break SW = no brake lights

I attached a picture for reference.

Any thoughts?

Thanks

My first thought is to contact Z Specialties and see how much they would charge you for a dash wiring harness.
