The backup wire is on the unit.

Ok that makes more sense to me now.

edit: Just looked over the installation book and it didn't lead me to believe that I need to hook the power wire up to the reverse wire on the harness. I'll just follow the video I watched on youtube. Sorry for asking the same question again. I'll figure it out sooner or later.

Rather than starting a new topic.

My cam has a power (Red) and ground (Black) wire. Is there a way that I could modify the wires somehow ie (add another wire) so that I could use the cam whenever plus when backing up? I haven't found a good explanation on this.

Just gotta make sure the cam will automatically show up when in reverse.

 

as mentioned in post #10 from the first page: all that you have to do for this is have the camera powered up (red to a switched power source, and black to ground) then the reverse wire from the avic has to be connected to a reverse signal from the car, then have it turned on in the settings.

Ok this is now clear as day, I take the reverse signal from the x920 and run it to like the back up lamp. Thats easy.

How could I be some dumb for not reading #10.

We all have to start somewhere I guess. Glad you got it working.

yea, dont worry about it, some times i tend to skip around and miss all the critical info, it happens bro.

so i am underway with this install finally . . . ground is easy, as is finding switched 12v. The mystery is the rear-view wire. I was hoping to use the one in the passenger side harness (grn/blk), but that didn't seem to go well - aka, when I went into reverse, nothing happened. also, the brown input kinda took over the x920, and that's ALL I could look at on the screen.

Obviously, something has gone wrong.

Given these clues, would you bet on a bad camera or a bad connection. Secondly, there is a confusing selection in the camera screen for "polarity".

Any thoughts on which is the correct setting there?

thanks

the polarity setting depends on whether the wire that you tapped into for the reverse, positive trigger means that the wire switches to 12v+ when in reverse, negative means that the wire switches to ground while in reverse.

As this may be beyond my electrical knowledge, do you know which of the two methods switches to what exactly. Method one being the grn/blk wires in the cluster beneath the passenger compartment, and method two being a connection to the reverse light at the back of the car. I do know that if you have the wrong one selected in the menu, and you connect to the opposite, the Pioneer locks you out of anything BUT the rear camera

you need to use a meter to test the wires before you hook anything up to them, the results from testing will confirm the correct wire and tell you the correct polarity.

thanks, i ran down to my local pros, who had a light tester for such a task, and we found the correct cable - all is peachy

awesome
