2003 explorer alarm disarm wire

Dont have factory alarm remote and installed Clifford Matrix alarm. All diagrams say alarm disarm is the GREEN/ purple; but, I found three GREEN/ purple wires in the bundle by the the kick panel.  One was a larger gauge wire than the other two so I used that one. Sporatically, factory alarm goes off after door is opened or goes ff for no reason and only stops with key in the ignition. Any ideas?

Installed Clifford alarm. There are 3 GREEN/ purple wires in the bundle. Used the larger gauge wire of the three. Factory alarm still goes off randomly (when doors opened). Only shuts off with key in ignition. No factory remote. Bought new remote, did not work. Any ideas for disarm wire???

sound slike you are just blindly connecting wires.

are you testing any of your wires?

if you have a test light or meter check all three wires and one should be a negative wire that will be it

Wow!!! blindly connecting wires?!? thanks, dude. yes I checked them and all were negative. I went through the diagrams and did not see what the other 2 wires are for. The car had the same factory alarm problems before.

you mentioned 3 wires in the kick and you decided to use the larger gauge wire of the 3. now that sounds like blindly connecting wires.

heres how to check it PROPERLY. if you are just looking for a wire that is resting at ground, you clearly have no idea what you are doing.

take your DMM(hope your using one) set DMM to 20vdc, red probe to constant 12v, black to wire you are testing.
take the key and turn it in the driver door to test the wire. If you turn it to unlock, the wire should go to ground and the meter will read 12-14vdc.

Ok, I'll try that tomorrow. GREEN/ purple is what every diagram/ chart I could find on 2003 Explorer says. Even the one on this website.

I have found it easier to get this wire GREEN/ purple (-) in the drivers door boot. It isnt in the kick panel. Most Fords harnesses from the door split behind the E-brake and some wires go up into the dash and some down thru to the DKP. Hope this helps.

By the way, I dont think tedmond was being rude. As I read your first post I thought the same thing he did. Next time maybe just put in there that you tested all the GREEN/ purples and didnt find what you needed and you wont have to worry about it.

Ok, maybe stating that I didn't start messing with wires in cars yesterday would have changed everything? or maybe not. I came to this forum looking for answers to problems, not to get treated like I've never seen a car before just because I just joined this forum. Anyway you look at it, HELP is greatly appreciated, irrelevant remarks...  I'll leave those for my kid's facebook page. Thank you for the help.

Maybe I can help since I own a 2002 Explorer with factory alarm and the 2003 is the same generation. The reason why the factory alarm is not always going off is that you can only set the alarm one of three ways. 1)factory FOB 2)pressing the bottom two buttons on the keypad outside on the drivers door 3)locking the doors while a door is still open.

My bet is that it is arming when you lock the door with the aftermarket FOB and either you or a passenger hasn't closed all the doors yet. Since this might be a rare issue, it seems like the cars factory alarm is intermittly arming.

Personally on my car I didn't even know it had a factory alarm until the above senario must have happened to me and the factory alarm went off. I went running around my house looking for the factory FOB to turn it off, LOL. I had to go back into the install and get my disarm wire off the remote starter and find the elusive PURPLE / green disarm wire in the car.

I experienced the same problem, it is not located in the drivers kick panel near the foot brake and I ended up grabbing it in the drivers door boot. Later on,(I own the car since new)my remotes died and it was cheaper for my to buy a new remote starter with more features then to buy 2 old remotes for the old system. While I was installing the new remote start, I was able to find the disarm wire in the drivers running board. There are 2 bundles of wires running down the running board, it is in one of them. There are a few PURPLE / greens in there, but if you carefully check(and I know you know how to as you clearly stated) you will find it. Make sure you check both harnesses as I don't remember which it was in, and there are a few to check. As stated earlier it is tested while testing for ground while turning the key in the drivers door cylinder.

Also, Negative trunk release was under the drivers sill for the rear seat. I think brown or tan with a stripe. It will test while pressing the button on the rear hatch. And also Negative door trigger with no light delay is light blue/white on the bottom left connector of the cluster. no need to remove cluster, comes straight down on the front bottom edge of the cluster. It is the door ajar wire for the cluster. This wire cannot be used for Dome Light supervision. You still need to use the BLACK/ blue (+) dome light wire for that in the drivers side sill.

Good Luck
