Hi everybody, this my first post here, i like this forum too much, i am very new in cars world, i got my new CX-9 five month ago, so i decide to install DVD Headrset for my kids, i got this on in the photo and decide to install it myself (i hope!!).
i fix it and pulled the wires through the back of the seats, but ....!!!! the problem that i haven't any idea about the car electricity so i am afraid to make shortage in the electrical circuit.
anyway, each device ending with fuse box and two wires (red and black) come out of it, my question is if I combine the four wires to be two wires ,two red in one and to black in one, and connect these wires to cigarette lighter plug is that will make any problem in the electrical circuit?
Or how to give the two devices power from the cigarette lighter?
Sorry .. too much talk but I want to be clear
