Roger, I have that monitor, and my understanding from reading through the many Amazon reviews is that the blue wire is intended to connect to the vehicle's backup-light circuit to automatically switch video to the rear camera when shifting into reverse (not turn on the monitor). Your idea is a very good one for FEL work. :thumbsup: I don't know if many compact utility tractors come with a backup-light circuit, but if the tractor has a backup warning beeper, the blue could connect to that.
It could be hooked up to a back up alarm like you said. I was thinking a switch could be added to the HST pedal and connect the blue wire connected to it so the monitor would change channels. It would be cool for loader work. Now I wonder how well the wirless cameras work. That would make a nice FEL cam.
My monitor and camera arrived late last Friday afternoon and I bench tested with a 12 volt battery in my shop Saturday. I will install first camera on front of tractor to get a better view of grapple, bucket, pallet forks etc. I did not get a chance to figure out how to use the blue (backup) wire. The instructions with camera and monitor that I received were all but useless. Maybe they missed sending the real instructions? I had to pretty much guess how to hook everything up so don't have a clue on how blue wire works. Think I will be happy to just select Camera 1 or Camera 2 from monitor controls.
I plan to create a temporary (maybe permanent?) magnetic mount so, I can find optimal location for front camera to achieve best view while giving camera some protection. Ordered a windshield mount today with 1/4-20 screw for mounting monitor in cab. Should receive it Friday. My plan is to mount it in upper middle of windshield which should help with outside light reflection, etc.
I also ordered monitor and camera from Amazon but, did not see if there was a way to order a second camera from same vendor? The rear looking 2nd camera will start out installed inside cab for protection and to keep it clean. Back of tractor gets pretty dirty during dry times.

You right, the instructions say nothing. I should have taken pictures of how I hooked the wires up.
I like your idea for the magnetic mount for the camera. What kind of mount did you order for the windshield?
There is usually a drop down box for you to select the quantity on amazon.
With the camera in the inside if you back glass is clean the camera should be clean.
