Looking for a way to bypass my Alpine. It takes two positive and two negatives. I put the +'s together and the 2 -'s together and that will not work once the car is turned off. I found that the positive is only used to turn the deck on than the picture is sent a negative signal. Can any help ?

Hello, Big King, I'll help you out.First of all, you will need a on/off toggle switch and a push button switch.Now, The only way to activate the auxillary ports while driving is to connect the yellow/blue parking brake wire to the on/off switch(black side of wire goes to yellow/blue wire and the grey side of wire goes to +12v).The push button switch go to the foot brake wire(yellow/black).One end of the push button wire goes to yellow black wire and the other end goes to ground........Now the important part,Once the switches are in place flip the toggle switch to the on position then off and press the push button switch 3 times and hold down on the third press.While maintaining your finger on the push button switch, flip the toggle switch on and let go of the push button switch after you flipped the toggle switch to the on position the second time. To sum up what I just said the sequence is toggle..on..off..pushbutton..1..2..3 and..hold..third..time)..Toggle..to..on..position..again..second..time..then..let..go..of..the..push..button..switch.this should activate the aux ports. Let me know if this works or not.I know this is a lot of things to remember but you will be happy once it's done.
