Auto Door Locks using a lock pulse generator

[JuneBug]

Thanks to xurav4 who started this thread:

Install automatic door locking upon Gear shift on 2007 RAV4.

and eitingon in that same thread, I found out about this little door lock pulse generator module from Directed Electronics:

Since I didn't want to use relays, and the price was right, I ordered one and installed it today. Seems to work great. It produces a 1 second pulse to lock the doors when I put the shift into reverse. But this module can do more. You can wire it to lock the doors immediately when you turn on the ignition. It can also unlock the doors when you turn off the key. Here is a scan of the first page of the instructions:

As you can see, it can produce a positive or negative pulse. On the RAV, I needed the negative pulse to apply to the pink lock wire, so I used the green wire. To trigger the pulse I used the violet wire which connects to the red wire for the backup lights. The +12 volts is on the grey wire on the same plug as the pink wires. And finally the black wire is connected to the ground bolt in the kick panel. There is a white plastic bracket at the bottom of that kick panel area, and it has an empty space where the module can be inserted lengthwise and it is held tight.

If you want the doors to lock when you first turn on the ignition, you need to connect the violet wire to the switched 12 volts which can be found on the blue wire in that same plug. If you want the doors to unlock when the ignition is turned off, simply connect the blue wire to the upper pink wire in that plug.

Thanks to everyone, especially xurav4 and eitingon for their fine efforts! This is a great mod!

Well done. The door lock pulse generator really is the way to go - much cleaner than the relay solution.

"Pulse generator mod?! I guess I am just low tech and cheap. If I want the doors locked or unlocked, I use my pinky and push the lock/unlock switch. :D

Thank you, James! This will be my next mod. Your posting of the details is much appreciated and look very helpful.

I might also see if I can find some orange LEDs to mount in the door housing to shine down on the lock and window buttons while I'm at it, but that's a topic for another thread.

I'll have to wait until it warms up, though. This is the wrong time of year to be outside wiring stuff up here in the northeast!

will this affect my rav4 (2007) with the keyless entry???

Nope! Mine works perfectly.

James-

Just to be clear, the Pink (door lock) wire is the middle wire in the lowest row of the lowest plug under the cowl cover. The grey (+12 volts) wire is in the same plug as the above Pink wire - is it the only grey one in that plug? Lastly, the Pink (unlock) wire is also in the same plug but it is in the second to last row all the way to the left. Is this correct?

TIA

CROW - if you have a volt meter, all of the wires are easy to test. It's always a good idea to test first...

Yep, that is correct, Crow.
