Hey, guys, just offering up an alternative method to disarming the OE ZJ alarm for those that don't want to create any new holes or cut any wires. I like to be able to easily restore things to their original condition as easily as possible (if ever needed) so here's what I did:
1. Remove all the screws holding in the door panel (see TS' picutre).
2. Remove door panel.
3. Peel back most of the plastic sheeting (just enough to access what you need to....which is about 1/5 to 2/3 of it). Try not to let it fold back on itself since the edges have an adhesive on them.
4. The violet wire with the yellow tracer, along with a black ground wire, go most of the way through the main harness in the door before branching off and ending in their own connector. This connector then mates to a ~2ft harness, containing green and black wires, that connects to the back of the lock cycliner. The 'green + black' wire harness that goes to the lock cylinder is held in place by sliding onto a bracket on the inside
of the door frame. You can remove it from the door frame by carefully sliding it off the post.
5. Once the 'green + black' wire harness is off the post, you can disconnect it from the 'violet/yellow + black' wire harness you need.
6. Create a jumper to plug into the sockets of the connector with the violet/yellow and black wires. This is what will ground the violet/yellow line. I found that the center conductor of a piece of regular household coax works quite well (just cut off the sleeving, dielectric, etc... and discard them). I had a piece of 18-gauge wires but it was a little too small so maybe a 16-gauge (or 14-gauge?) would work well. I just formed a U-shape out of the copper conductor and trimmed the ends so that it didn't stick out of the connector.
7. Once you have your jumper cut/shaped to your liking, insulate the portion of it that would be exposed when it's plugged into the connector.
8. Insert the jumper and cap off the connector. I masked it off with electrical tape.
9. Cap off the other connector and slide it back onto its retaining post inside the door frame.
10. Tie off the harness you just jumpered to the rest of the main door harness (I used cable ties).
11. Replace the plastic sheeting in the door.
12. Replace the door panel.
13. Replace the screws for the door panel.
Your power locks will still work and when you lock your Jeep you'll no longer see 'Security' light up on the dash.
Door panel and sheeting off:
Violet/yellow + black wire harness disconnected from lock cylinder harness:
Other end of the lock cylinder harness (black connector):
Jumper shaped, cut, and in place:
Both connectors capped and tapped off:
Violet/yellow + black harness cable tied to main door harness:
Plastic sheeting back on:
Hope this is useful for anyone that doesn't want to cut any wires or tap any extra holes.
BTW, does anyone know what the connector to the left of where the armrest post is? It wasn't connected to anything when I was taking the door panel off and I don't know what it's for.
