SOURCE: I just installed an after

In the wiring diagrams there is a COMPUTER DATA LINES SYSTEM wire. From what I have read the radio won't cause the car not to start. Did you make sure you didn't drain the battery? Is the Theft Deterrent light on? If it is you're going to need a scanner to get the codes. This is what the Theft Deterrent system does with the radio.

I think if the Theft Deterrent light is on you will have to start there if not just diag a no crank condition.

2015 Ford E350 Super Duty Stereo Wiring Diagram

I would see if there was an adapter harness for the stereo to your harness first. When you replace the factory stereo, you will loose many functions the radio controls. You will loose chimes, you can't reset oil life and other things. It will take a scanner to reset or change certain options. $90 to throw a scanner on a vehicle where I work. The radio you get has about 12 wires to it. The factory harness has about 20. Those extra wires are data lines. You don't want to patch into one of them. And some of the data wires are the same color as speaker wires. Also if it has an amp in it, that is additional wiring that has to be done. The aftermarket won't run it.

I bought an after market in dash stereo for my 2005 Pontiac sunfire. I have now tried 3 different wire harnesses that were for my year and none of them fit. I called my local electronics store and was told...

Hello Megan,

It sounds like there is a specific wiring harness required for your Sun Fire.

First place I would start is with the compatibility of the after market stereo. Did the stereo manufacturer provide an application list with the stereo.... that provides the makes and models of vehicles it will work in?
If your stereo purchase is new, can you exchange it for a unit that is compatible with your car, including the necessary and correct wiring harness?

If not....then you will need to purchase the harness that has been identified as correct for your vehicle.

In most vehicles the "chime" is located in the dash around where your 4 way flaser is. It could simply be the door switch also which is a little button that depresses when you close the door to open the circuit shutting the dome light and chime off. They are easy to change and inexpensive. Hope that helps.

I have a 98 grand prix an I was wondering how to install it.. I have a harness that came with it but my factory harness won't fit. I was wondering if j have to rewire the factory harness to my JVC...

You need to go to your local "best buy" or electronics store and ask them for your car's "stereo wire harness". This will convert the wires from your car to match all the colors from your deck. (green, purple, white, gray, blue, yellow, red, ect. Same on all after market decks. All brands use the same wires) Take that new harness and your deck harness, twist the matching wire colors together, tape them with electrical tape, plug the harness back into the car and deck, and it should be good. Click, click, done. Remember to plug the antenna in as well before you get the deck in.

How difficult is it to install an after market sony stereo in 2004 chevy venture. My CD player broke and I want to upgrade. I am somewhat of a Saturday mechanic but dont want to et too complicated.

The problem with doing an after market stereo yourself is that your door chimes run through the stereo speakers amongst other things controlled by the body control module.. You may be better off picking up a used one from a salvage yard and saving yourself some headaches.
