Pioneer Stereo in a Jeep Cherokee

Did you use a wiring harness from Metra or Ai ? or did you hardwire it into the Jeep ? Check the fuse ( 10 amp ) on the back of the radio to ensure that it is still good. If this is burned out, then replace it and see if it will start up. If it burns out again, then you have a short on your power wire somewhere along the way.

Another thing is to make sure that your fuse in the fuse box ( or engine ) is still good. When the thieves stole the original stereo they may have grounded out the wires and burned out the fuse in the fuse panel. Check here first.

I wired it into the Jeep.  The original wiring was hanging out of the dash, so this was a pretty easy job.  I checked the fuses in the radio and the Jeep's fuse box.  They appear to be fine, but I replaced them anyway.  There still appears to be no power to the radio.  It won't turn on.  Thanks for the help, though.  Any other suggestions would be appreciated.

Where did you ground the DEH-P1400 to ?? Jeep has a grounding strap that needs to be grounded in order for the system to work properly. Check this out and post your results if you haven't already done so.

I connected the radio ground to the ground wire on the Jeep.  This is a black wire that was bundled with the others.   I didn't see a grounding strap (and I'm not sure that I'd recognize it if I did).  Were should this be located?  Is it something that needs to be hooked to the radio body or one of the wires?  Thanks for all the help!

The strap , like you said, would be obvious. If it wasn't there, it probably did not have one but there will be another signle black wire outside of the two plugs with a femail connector on it .  Also,  did you test all your wires before you hooked them up to the factory plug ? Here's a cross reference diagram for each of the wires that are on the plug ( Make sure that the wires that you attached from the Pioneer deck are going to the correct wires on this plug ) :

The graphics are not displaying with your last reply.  I will check for the grounding strap and let you know what I find.  Thanks.

That's funny cause I can see it now ?? Try to refresh the page again.

you should check and make sure that your power wires are supplying 12V correctly.  If you have a multi-meter, this is an easy task, and if you dont have a multi-meter, go pick one up from Radio Shack, Sears, Home Depot etc.  These things are really handy.

Make sure your constant 12V is always supplying 12V.  Then check the switched 12V before turning the ignition or to the accessor position, and it shouldn't read any voltage, then when you turn the key, it should read 12V.  I always use the cigarette lighter slot for my ground when I am testing wires.

Good luck!

I don't have a multi-meter, but I will pick one up tonight.  Thanks for the suggestion.

Also, I think the constant 12 v wire may not be hooked up correctly.  Would this cause the radio not to work?  I also don't seem to have a place to connect the Dimmer and Illumination wires.  Is this a problem?  Thanks.

Hey Velocity.

You have the pictures saved on your hard drive under
C:/remote_starter_diagrams/OEM%20Stereo%20Removal/

They wont upload in the forum.
You would need to upload them somewhere with webspace and fix the paths.

Hey sparkyssb; the probelm is fixed, I just linked it to the actual page on the website.

do you mean the Pioneer has a dimmer/illumination wire?  I think if the Jeep doesn't have illumination leads (mine didn't) I connected them to the switched power lead, the one thats on only when the car is on, that way the illumination circuit will only be powered when the car is on.

Yeah jlowens, the Multimeter will be a friend of yours for a looooong time!  They come in handy all the time.  Lets say you TV remote batteries go dead, and you have a bunch of batteries laying around in a drawer or something, you can use the meter to see which batteries are still any good.  There are a ton of uses for it, it will be money well spent, especially for the do-it-yourself-er.  Good luck.

If you do not have the 12 volt constant hooked up porperly, the deck will not keep memory and will not power up. If you did not hook up the dimmer / illumination wire, it is not a big deal., the deck should still work regardless.

For those of you that may be interested, my stereo is now working.  It was a problem with the power.  The multimeter did the trick.  Thanks to everyone for the help.  I'm not sure I would have got it going without you!
