have a 2001 Camry LE I put a remote starter in. It had two wires for
the doors and directed me to connect the starter unit Lock wire to DARK
BLUE/WHITE, and starter unit Unlock wire to DARK BLUE. The Remote
Starter was a low end unit and used a single button to Lock/Unlock on
the remote. When I hit the button it either locks or unlocks all 4
doors. Perfect. I miss the dual pulse lock/unlock (unlocking only the
driver's door on the first press), but easily accepted it in lieu of
carrying two remotes.

I just purchased a higher end starter/alarm that separates the Lock and
Unlock, and supports dual pulse. It has three wires, but it's
schematic shows it to hook up only the + and - trigger wires, and to
the same wires as the one in there now.

POWER LOCK DARK BLUE/WHITE (TYPE B)
See NOTE *5 @ ORANGE PLUG BOTTOM OF FUSEBOX

POWER UNLOCK DARK BLUE (TYPE B)
SEE NOTE *5 @ ORANGE PLUG BOTTOM OF FUSEBOX

LOCK MOTOR WIRE BLUE/RED (+)
@ ORANGE PLUG, BOTTOM OF FUSEBOX

NOTE *5 the LOCK and UNLOCK wires are 18 gauge and WILL ONLY METER
while turning the Key in the PASSENGER DOOR KEY CYLINDER, they will not
meter when using the power door lock switch.

This got me wondering if the dual pulse is going to work. Digging into
the docs (and they are lacking to say the least) it appears it is not
sending two pulses.. Just one....

This leads me to believe I'm not going to have dual pulse in the new
unit. It will be all 4 lock or unlock when the corresponding button is
pressed. If I'm right, this sucks.

Digging around on the internet, I happened across a wiring diagram on
a link from here that's slightly different. It lists the same two wires
and the Power Lock and Power Unlock, but it also lists two more..

Lock Motor BLUE/RED
Unlock Motor BLUE

OK.. so maybe I'll need to use the other two wires. 5 minutes of
troubleshooting should answer that (or maybe one of you can even save
me the 5 minutes *hint* *hint*). ;-)

But here's yet another monkey wrench in the gears...

I found another newsgroup posting that says the OEM repair manual lists
them as:

Power Lock: Wht/Red LIGHT GREEN (-)
20 PIN CONN IN DRIVER'S KICK PANEL ***

Power Unlock: Yel/Red DARK GREEN (-)
20 PIN CONN IN DRIVER'S KICK PANEL ***

ARGHHHH!!!

It won't take much to troubleshoot which to connect to if it's one of
the three. I can probably even determine it without stripping any
insulator by probing the wires; or if I'm really ambitious, just open
the door up and trace the wires going to the key lock.

But I'm wondering if it's going to require some type of complicated
relay configuration.. Let's just say.. I'm not feeling extremely
confident tearing the car apart and getting stuck there for a day or
more. Can anyone shed some light on this?

Something else I've found a bit confusing is every piece of
documentation I've found states I should have a transponder in the car,
yet I don't. Can someone confirm whether at least some 2001 Camrys
were sold without transponders? I've had several keys cut, and never
had any problem with them. The good news is at least I didn't have to
deal with.

If anyone can give me some insight, I'd be eternally grateful. :)

TIA,

Joseph

Joseph,

Some 2001 Camary has a transponder. Very easy to tell. If you have a cut key for your vehicle and not from the dealer. If you stick the metal key in the cylinder and the car start. YOU HAVE NO TRANDSPONDER!

"Lock Motor BLUE/RED
Unlock Motor BLUE
OK.. so maybe I'll need to use the other two wires. 5 minutes of
troubleshooting should answer that (or maybe one of you can even save
me the 5 minutes *hint* *hint*). ;-)"

Don't bother with this. This is directly connecting it to the lock motor it self.

Door locks.

|       POWER LOCK|dk. blue/white *3   |- |org plug bottom of fusebox |
|     POWER UNLOCK|dk. blue *3        |- |org plug bottom of fusebox |

They are negative polarity. Yes you will need a dual pulse to get it to unlock. Don't bother with all other information you that you came upon. You will just only confuse yourself. It's very simple. Stick with what works and what wire is already existing. Don't make it anymore complicated that it needs to be. You have the lock and unlock wire already from the old unit. Just connect the Lock and Unlock wire from the new unit on to it and you are all done.   Don't bother with the third wire on the new unit. It is usually for priority door lock. The Polarity is Negative. Again, don't get too technical, work within your limit of knowledge and understanding and you will build a lot more confidence.

OK.. I'm finally here doing it...

Installing a Bulldog Deluxe 500. It supports dual pulse unlock with a separate wire. I'm a little less daft now that I installed the same unit in my Jeep with aftermarket door actuators I installed. I just need to isolate the wire (-) that unlocks the driver's door only. The only real point of confusion is the factory lock/unlock on the unit and how that affects things.

If any of you experts out there could read over my ramblings below and let me know if I'm on the right course, it would be much appreciated.

Also, if anyone knows the specific wires to the drivers's door to lock/unlock you could probably save me a lot of tracing time :)

--Ramblings begin here--

I know my lock system is Type B, so to activate the locks I need to provide a ground to the wires to lock/unlock

Lock Dk Blue/White

Unlock Dk. Blue

I'll need to find out what the + wire to the driver's unlock is as well to see if it is resting at +. These things get a bit confusing in reverse polarity circuits!!!

I'm hoping I can just send it a - and unlock it, but I'm prepared to add relays/diodes if necessary to feed it whatever it needs to get it to unlock. Unfortunately I can't breadboard this one...

Worst case scenario I have to put two relays in and send it both + & -, and rest it the way it is. By knowing what both wires are, I should be able to do it with a single relay. My uneducated guess is both rest in a + state, and they tap into the line on one side or another to close the circuit in whatever polarity desired. If this is the case, I'd just need to tap into it and do the same with a relay.

--End Ramblings--

Thanks!
