Tried the front camera white wire to power which turns it on a week ago and it didn't work.
Screen didn't go black and no voltage on the camera lines.
This week I hard wired accy. line power to connector X322 pin 3.
Tonight I checked wiring which was OK.
Put white wire pin 7 to power and the screen went out.
Checked the power going to the camera lines and it was 6V just like the rear.
The print showing 12V is a mistake. Now it makes sense since both front and rear are 6V.
Paul Kim at BOYO said that their cameras will work at 6V. The specs. say 8V minimum.
When I released the power from pin 7 the screen didn't go back on.
Didn't have a camera or the speed line connected etc.
Have to look into that.
I put the shift lever in reverse and then out and the screen went on after the normal few seconds.
Will have to wait and see how it works with a camera hooked up.
Getting closer to the rush or not rush.
