06 honda ridgeline reverse cam

I am working on a 2006 honda ridgeline with a pioneer d3 and using a backup cam. I found out the the reverse signal is green and can be found above the drivers side kick panel fuse box. I found this and it had 12v on it only when in reverse but it is no longer working but the reverse lights still come on when put in reverse. My question is is there anywhere else to catch it at or would anybody know why the first wire i found is no longer working. I checked all the fuses inside the call and the 2 fuse boxes under the hood. Any help would be greatful.

thanks
