I noticed the reverse sense wire has a resistor on it. I am in the middle of troubleshooting why my reverse camera does not come on in revers anymore. It worked fine for a couple of hours. I will pull the radio, but I need to know, is this resistor needed? Im thinking I might have to replace the wire.

Thanks

nope, you can use a 1/4 amp fuse, will do the same job.

All fixed.. I had 12 volt in reverse at the connection to the light, but no voltage registering at the unit. No blown fuses, so a little wierd. Then I noticed that the resistance measurement was a short. So, even though it didnt blow a fuse, I was able to track down a pinch in the wire. The only spot that I forgot to zip tie out of the way from those pesky metal interior clips endend up getting pinched.

So, a quick repair, and its all fixed. I bet that resistor was all that kept me from blowing a fuse.

Thanks for your help!
