installing a sunvisor monitor

i am having some problems installing a sunvisor monitor. The 8" tft lcd was pre mounted in a sunvisor, which i mounted and ran the wireing through the molding and into the floor. I cannot seem to figure out how to power it. It has a black box that plugs in and provides 2 video wires ( one input, one output) a video input on the box, and 4 loose wires, a black, a blue, a yellow, and a red. The diagram supplied only shows 3 wires??? Can some one help me and tell me how + where to get the power from. I am not sure how many amps it needs but requires a standard 12v.

I had the same wiring configuration on my Moble TV 5'' monitors a few years ago...i know the black is bround, yellow is constant, and red is ignition....I forgot what the blue wire was for..but i think i still have my manuals for them tvs in my garage..ill check and see...but im pretty sure you should be able hook them up with out the blue wire

Thanx, where can i hook the constant and the ignition (red and yellow) wires too then?

run a wire from your battery fused, and an ignition from your fuse box, also fused

umm ... how do you do that? Where can i get fuses to use?

Doesn't matter if the constant power comed from the battery or the ignition switch or fuse box. I prefer the ignition switch myself, but what ever is best access for you. Fuse this wire is a good suggestion and I'd use a 5-7.5 amp fuse.

That will work too, usually when i do video systems i run a fused 10 guage from the battery...because usually you have all kinds of stuff to hook up, like dvd players, inverters, video amps, etc.....and fuse each of them indiviually of course

where is the ignition switch, and how do i run power from it? I know where the fuse box is but how would i use that method? also once i have that source of power what do i do with the 2nd (red) wire.

What kind of car is this and also what other RED wire ? You only mentioned one in your original post ?

im sorry, yes there is only 1 red wire. I was ust asking where that one was run to if the yellow was the constant source. its an 04 denali.

The blue is probably a remote turn on wire. Yellow is power. Red only allows you to turn it on once the key is in the accesory or run position. Then blue only turns on the unit once you turn the stereo on. Hook it up to your power antenna wire (also blue) on your car stereo.

You still havent answered my questions. Ok so if i hook the yellow wire up it will turn on? You need at least a complete circuit ? I am soooo confused. This means that you must use two wires. If i am wrong just let me know.

RED ( assuming that this is the ignition wire ** MAKE SURE OF THIS with the install guide ) - will need to be hooked up to the PINK wire at the ignition switch

YELLOW ( assuming that this is the constant wire ...same as above ) - this will go to the RED wire at the ignition harness

BLACK- GROUND

BLUE - might be a remote wire, but try leaving this connection out until you get the other 3 connected and try to turn on the screen. If you get nothing, test to make sure that the BLUE wire doesn't have an output of any sort on there and then try running a jumper wire from the switched ignition wire to the BLUE wire as this will be the same as a remote turn on wire from an aftermarket head unit.
