Remote starter hi someone help me my problem in my 2004 grand cherokee i install remote starter but we cannot find the Acc. and Ign1. wire from the harness i fund already the starter, ING2. and the constant 12V wire its work the car but the problem now the radio,and some control is not work. somebody help me where i can find the solution for my problem thank you

sure inside, radio.
check all fuses first.
make sure all 3 power wires are in fact at 12v.
if not , fix that first.
power ( goes to IGN1.
Dial (goes to dash park dimmer ckt)
memory (hot all the time)

a common item on this vehicle is one or more wires breaking in the wire harness, look at the door wire harness that goes between the door itself and the body. strip the covering off the harness and check the individual wires for breakage or corrosion. If there is room and not too many broken you can have them repaired, otherwise on some models yuo can buy the section of wire harness from the door to the body and just replace the assembly.

Check the wiring harness from the door jam to the door pull back the rubber boot and check wiring harness for broken wires and splice as necessary. Had the same problem.

It is located behind the starter motor. It is secured by one bolt and has a wiring harness. First remove the two bolts that secure the starter motor to the transmission bell housing. Move it out of the way to access the crank positioning sensor

I had the same problem recently. The dealership diagnosed the pblm as a corroded wire in the door frame that is responsible for all power windows and power locks locks. A simple rewiring and resoldering (approx. 150 CAD$) fixed the problem.

Grand Cherokee oxygen sensor locations for 4.0 and 4.7 engines







Four wires (circuits) are used on each O2 sensor:

• 12–volt feed circuit for the sensor heating element
• Ground circuit for the heater element
• Low-noise sensor return circuit to the PCM
• Input circuit from the sensor back to the PCM to detect sensor operation

O2S Sensor removal Never apply any type of grease to the oxygen sensor electrical connector, or attempt any soldering of the sensor wiring harness.
WARNING: THE EXHAUST MANIFOLD, EXHAUST PIPES AND CATALYTIC CONVERTER(S) BECOME VERY HOT DURING ENGINE OPERATION. ALLOW ENGINE TO COOL BEFORE REMOVING OXYGEN SENSOR.
1. Raise and support vehicle.
2. Disconnect O2S pigtail harness from main wiring harness.
3. If equipped, disconnect sensor wire harness mounting clips from engine or body.
CAUTION: When disconnecting sensor electrical connector, do not pull directly on wire going into sensor.
4. Remove O2S sensor with an oxygen sensor removal and installation tool.

02S Sensor installation
Threads of new oxygen sensors are factory coated with anti-seize compound to aid in removal. DO NOT add any additional anti-seize compound to threads of a new oxygen sensor.
1. Install O2S sensor. Tighten to 22 ft. lbs. (30 N·m) torque.
2. Connect O2S sensor wire connector to main wiring harness.
3. If equipped, connect sensor wire harness mounting clips to engine or body. When Equipped: The O2S pigtail harness must be clipped and/or bolted back to their original positions on engine or body to prevent mechanical damage to wiring.


Hope thats help (remember comment and rated this).

Hi John,

I'm not sure about the 2004, but my 86 Cherokee has a wire bundle beneath the rear bumper. A test light and yelling to a friend in the drivers seat made wire identification pretty easy. (I don't get up that easy any more from a prone position ;0)

AND this will help with the actual hookups.

Click here for a cheat sheet I wrote when I finally got tired of looking up wire colors.

Best regards

either master control went bad or there's a break in the wiring in the door harness where the wire goes through the rubber boot to the front door post

in most cases the wiring is already there, it is cheaper for the manufacturer to use one harness than many different ones, I know this is true on GM and Ford, should be the same with Chrysler products as well.
