Need wiring schematics for a 1996 dodge caravan stereo hooking a new one up but dont know what wire is what theres no diagram on the stereo

a reputable car stereo place will sell you a wiring harness for your vehicle and after market stereo, that tells you which color wires to hook to what.

Can you take the van to a local family owned shop near by that could hook them up for you reasonably? Google the manufacture and contact them or take it too a dodge garage? The wiring from the motor should be very basic, like 1-3 wires and not costly or time consuming to hook back up. What brand lift do you have? The more info you give us, the more help we can be!

Will the color code do, or do you need the actual wiring diagram?

i recommend going to walmart or car toys and buy a wiring harness made for your vehical that way you dont have to match with the stereo wiring sometimes accurate diagrams are hard to find.

If your puting in a aftermarket stereo system, they make adapters that will plug into the factory harness and have a diagram of what to hook up to your new stereo. They should have one of these at a stereo store or even auto parts or Wal Mart. I had to put one in my 89 Caravan and 88 Prelude. I got them from the local stereo store and they were about $12 bucks or so. Depends on how much your stereo place overcharges.

Hope this works for you....

YOU WILL HAVE TO TRACE THE WIRES OUT, DO U HAVE A SEPERATE AMPLFIER? MANY OF THESE VANS DO, IF SO THAT IS THE PROBLEM.

Do yourself a favor and run to audio store or even autoparts store & get an adapter plug/harness, cost is a few bucks but well worth it. It plugs into factory harness & you wire your new stereo to it according to diagram with new system.

google it car stereo wiring diagrams

wal mart sells after market plags for this car
and they are around 6 to 12 dollars and include the diagram to wire it in (if the factory harness no longer exists)
