I did a couple of searchs and didn't find anything on this, so apologies if I missed something.

This is about a tenth of a mod that takes less than 30 minutes (if you're moving slow).

The goal of this mod was to extend the range of the "factory" alarm. This applies to the RS3000 alarm.

Using my remote as a test unit (battery is fairly old, I'm about 4-5 feet away typically when it starts working) I was able to extend the range to well across the street, and even further as long as I had line of sight to the drivers side B pillar.

To reroute the antenna:

1. Find some wire that works. I used some speaker wire I had handy. If you had an actual antenna (it would need to be long, narrow, and fairly flat) that would probably work even better.
2. Pull the bolts on the seat (2 front, 2 rear).
3. Tip the seat back and disconnect the wires from the seat. I simply tipped it up on top of the center console to move it out of the way, but you could also move it onto the back seat.
4. On the single 4 pin plug (that has one grey wire in it), snip the grey wire a fair way back and connect your new wire via the method of your choice (solder or mechanical connector).
5. Slide the new wire under the carpet to the door step. I went along the ridge where the other wires were ran to make it easy.
6. Run the wire up the drivers side B pillar. I simply looped it over the top of the seat belt mount, and down a foot or so on the opposite side.

Initially (as you can see from my pictures) I ran a double wire and connected it back to the original antenna. This actually decreased the range to about that of stock.

I did several tests for range:

1. 4 pin completely unplugged (no antenna). About half the range of stock.
2. Stock antenna. About 4-5 feet range.
3. Double wire running up the B pillar and back down, terminating at the alarm. About the same as my final solution.
4. Double wire running up the B pillar and back down, attaching to the stock antenna. Same range as stock.
5. (Final solution) Single wire running up the B pillar towards the front, and hanging down about a foot on the back side.

Your range will be greatly increased no matter where you stand, but I found that the best range was with direct line of site to the inside of the drivers side B pillar.

Which makes sense as the only thing blocking the signal is glass and the soft cover over the seat belt mounts. Any other angle has metal blocking the signal.

Couple of crappy cell phone piccies below.

In the first pic, you can see the entire box. The 4 pin connector with a single grey wire is at the top.

Second pic has a zoomed in pic of the connectors. Note that in this pic I had the double wire hooked back into the factory antenna, which decreased the range. With the way I would recommend doing it (and how I'd do it in the 's rig) is to simply leave the grey wire loose, so you completely reroute it.


An alternate suggestion I found when searching for this was to find the end of the grey wire (ending somewhere around the steering column) and extend it up the A pillar. I found that getting to that area was far more difficult that getting under the seat, and would greatly increase the time to do the mod.
