Chrysler Repair: 99 Plymouth Voyager strereo, headlamps, interior lighting problem, factory wiring harness, plymouth voyager

Question
hello, i attempted to put an aftermarket stereo in my wifes voyager. However the aftermarket wire harness wasn't the right one ( Box stated for 84 on up Chrylser vehicles ). Anyway, i went against my better judgment and cut the factory harness and hooked everything up and it wouldn't turn on. So, after that happened i rewired the factory harness and hooked it up to the factory head unit and it still wouldn't turn on. The stereo would light up but no clock no sound, the speakers would pop once when i first turned it on. On top of all this the only way to get the headlamps, interior lights and horn to work was to have the vehicle on and running. When i turn the vehicle off or even just to the on position everything still wouldn't work.  Do you think you have a solution for me?

Hi Devin,
I saw this question in the "pool" to which it has been sent and realized that it is the same as that from Heather to which I responded the same day. Let me know if you still need help.

Answer:  Hi Heather,
There are two fuses that supply the audio circuit: fuse 8 (10 amp) in the fuse box under the dash, and fuse 28 (10 amp) in the box in the engine compartment. I suspect that those fuses blew because the instructions for wiring up the stereo to a Chrysler vehicle are wrong and so those fused power wires were inadvertantly grounded. I would disconnect the new stereo and then reconsider what it is that you attached to the pink wire (which carries 12V all the time from fuse 28 and powers the interior lights and some functions of the body computer, and to the red/white wire (which carries 12V when you turn the ignition switch to run position and powers part of the radio) of the original wiring harness as for some reason both those wires are shorted to ground which blows the fuses. If you can tell me what the instructions/wiring assigments of the new harness are supposed to do I can probably tell you where you have gone wrong.
