Hey guys, I thought I would share with you all my remote start experience on my 2004 Jeep Grand Cherokee
Total install time... 1.5 hrs
Equipment you will need...
1. Avital 4103 Remote Start & Keyless Entry System D2D compatible $75.
2. Expresskit DBALL Integration / Bypass Module $50.
Before we begin, let me start off by saying, although this is relatively an easy DIY install, if you feel you're not up to the task or do not really know what you're doing, leave it to a pro. The wire colors I have stated are what I used on my 2004 Jeep Grand Cherokee, and from my research should be the same for all 99-04 Grand Cherokee models, but DOUBLE CHECK all yours to be sure. NEVER just go by what they say the wires are on paper, always TEST THEM to be sure!
A. Remove the plastic panel directly underneath your gauges, by prying it up and out. There are no screws that hold it in place. It simply will pop off.
B. Remove the large panel under your dash (the panel across your knees). It is held in place by a total of 5 screws.
C. Remove the steering wheel column cover. One recessed philips screw hold it together, and then you simply pull the two halves apart.
Now you have access to all the areas of your vehicle where you will need to tap / connect into to install your system.
A. On the DBALL module, connect the PINK (+) ignition input lead coming from harness 10 (there are five harness inputs, labeled 2, 12, 14, 4 and 10) to the YELLOW (+) ignition output of the Avital 4103.
B. Tap the VIOLET / YELLOW J1850 lead coming from harness 14 on the DBALL module to PIN 2 on the Jeeps OBDII diagnostic connector.
C. On the bottom side of the steering column, you will find the key immobilizer module. Cut the wire coming from PIN 3 (DARK BLUE / WHITE) and connect the immobilizer side end to the ORANGE / YELLOW wire coming from harness 14 on the DBALL module, and then connect the car side end to the YELLOW wire coming from harness 14 on the DBALL module.
D. On the left side of the steering column, you will find the headlight switch. Tap both the VIOLET / GREEN and VIOLET / BROWN wires coming from harness 12 on the DBALL module to PIN 11 (YELLOW) on the white headlight switch connector.
E. On the bottom side of the steering column, you will find the ignition switch connector. Tap the two RED 12V high current input wires coming from "large gauge starting harness" on the Avital unit to the single RED wire on the ignition switch connector. Tap the PINK ignition output wire coming from "large gauge starting harness" on the Avital unit to the DARK BLUE on the ignition switch connector. Tap the VIOLET starter output wire coming from "large gauge starting harness" on the Avital unit to the YELLOW on the ignition switch connector. Tap the ORANGE accessory 1 output wire coming from "large gauge starting harness" on the Avital unit to the RED / BLACK on the ignition switch connector. Tap the PINK / WHITE ignition 2 output wire coming from "large gauge starting harness" on the Avital unit to the BLACK / ORANGE wire on the ignition switch.
F. Connect (or ground) the BLACK / WHITE neutral safety shutdown wire coming from the Avital 4103 unit.
G. Connect (ground) the BLACK ground wire coming from the Avital 4103 unit.
H. Plug in the extended range antenna to the Avital unit. Route and install in an appropriate location.
I. Plug in the valet / programming button to the Avital unit. Route and install in an appropriate location.
That's it for the wiring! You can tie up or cut all the extra unused wires and leads. Now it's time to program the module for D2D mode and finalize the installation.
A. Connect the D2D harness to the Avital unit but NOT to the DBALL module. Now connect harness 10, 12, 14 to the DBALL module. Press and hold the programming button, then connect the 4-pin D2D harness. Wait until the LED turns on ORANGE then release the programming button. The LED should now be RED. D2D connection is now complete!
B. To program the key bypass, insert the key into the ignition barrel and turn it to the ON position. The LED turns on solid GREEN for 3 seconds and the turns off. Turn the key to the OFF position and remove the key. Bypass is now complete!
And you're done!!! Give yourself a pat on your back!!!
Go ahead and test the system out, and if everything's working as it should, it's time to zip-tie and clean everything up. A good place to secure both the Avital unit and the DBALL module is right behind the fuse panel. It's a tight space, but everything does fit there nicely.
Naturally you can use any remote start / keyless entry system, but one that is D2D compatible (as with the the Avital 4103 and most late model Viper systems), really does simply everything. It eliminates the need to cut, tap and splice a dozen plus more wires.
Good luck and enjoy!
