This is a basic Remote Start with keyless entry Pictorial for the 2002 through 2004 Toyota Camry. This car was a basic 2004 Camry LE with the 4 cylinder engine, automatic transmission, no Factory Alarm, no Auto Headlights and no transponder based engine immobilizer.    As such, this Pictorial will not include info on a bypass module and will focus on this particular car and its' specific needs.
Vehicle considerations :
1. No need for a bypass module.
2. Common Type B door locks
3. To duplicate the factory remotes, trunk release should be included but it is a 5 wire REV system.
4. The car has two Ignition wires, two Starter wires and one Accessory wire, necessitating an additional relay.
5. The Factory remotes are in-op while the engine is running. A R/S w/keyless entry is a good idea.
For this install a Compustar CS800-s system was chosen.   There are many other systems that will handle this car, such as Prestige APS57E, Avital 4103LX, Viper 4105V and Ultra Start U1272, to name a few. Additional parts include two 10 Amp mini-relays, two inline fuse holders with 10 Amps fuses, two 1N4004 diodes and a mercury tilt switch. The mercury tilt switch is optional as you can use the R/S kit provided hood pin instead.
Please note that Bulldog Security has a great write-up on this vehicle with plenty of photos that should be reviewed and used to assist during the install. Below is a link to Bulldog Security :  http://www.bulldogsecurity.com/bdnew/vehiclewiringdiagrams.aspx
Here is the CS800-s to 2004 Camry that was used :

For the hood pin wire, firewall pass through can be had at the main harness grommet located high above the gas pedal. Here is a photo on the hood pin wire coming through that grommet on the engine side :
2002-2004 Toyota Camry Remote Start w/Keyless Pictorial -- posted image.
There are many good places to attach the Chassis Ground wire. I used a self-tapping metal screw and ran it to the heavy dash cross pipe. There is a large cavity behind the fuse box to secure the CS800-s brain.
That about does it for the wiring. There are a few programming changes that should be made to the CS800. To run in Tach Mode change Feature 2-04 to option 2.   You must also do a Tach Learn. If you want all doors to unlock at once, change Feature 1-03 to option 2, double unlock pulse. Being as the car does not have a factory alarm system, you can set the trunk to release without first unlocking the doors by changing Feature 1-10 to option 3. If you need a longer R/S run time than the default 15 minutes, see Feature 1-07. Another option you might want to change is the Horn honk, Default is after a second Lock command. See Feature 2-08 for more options.
Test everything and button it up.   Remember to use a Digital Multi Meter to test vehicle wires and make all the wire connections with a quality soldered joint.
Soldering is fun!

Hey Kreg!
Great info! Getting ready to install a CS4900-s in my 2004 Camry and was wondering if there is much of a difference between the two units. I guessing the basic wiring between the 2 won't differ much.
Thanks in advance!

Good choice! The CS4900-s is a nice unit.
For the most part, the wiring is the same. The CN1 connector is identical between the units. The CN2 plug is somewhat similar to your CN3 connector but go by the signal name instead of Pin location. The wire colors are pretty much the same but the Lock and Unlock wires are different colors. Your main issue will be getting a (+) Starter2 Output from the CS4900-s to properly power the Camry's Starter2 circuit. The CS800-s makes this easy with a dedicated (-) Starter Output that I used to control a mini-relay. The CS4900-s can do the same thing but would need a programming change to Special Option Group 2.   You could re-assign either of the unused Rearm or Disarm POC outputs to be a Starter output.   The big problem is that you would need the OP-500 programmer to do this. It can't be done with the remotes like you use to change options in Groups 1 through 4.    Now for the really bad news, the OP-500 goes for around $100. There is a way around this if you don't mind a bit of extra wiring.
Remember, the goal is to supply the cars two (+) Starter wire with separate, isolated power, so you can't just connect the CS4900-s thick Yellow wire to both vehicle starter wires. Buy two 30/40 Amp SPDT relays with pre-wired sockets, two inline fuse holders and a 25 amp and a 10 amp fuse. Figure about $15 for the parts. Here is the wiring :
Starter 1 Relay
Relay Pin 85 to Chassis Ground
Relay Pin 86 to CS4900-s CN1 Yellow Starter output
Relay Pin 87 to +12V constant through 25 amp fuse
Relay Pin 30 to Camry Black/White Starter1 wire, Pin 8 of main ignition connector
Starter 2 Relay
Relay Pin 85 to Chassis Ground
Relay Pin 86 to CS4900-s CN1 Yellow Starter output
Relay Pin 87 to +12V constant through 10 amp fuse
Relay Pin 30 to Camry Black/Yellow Starter2 wire, Pin 1 of main ignition connector
You will use the CS4900-s Starter output to control two relays. Each relay will supply isolated power to one of the Camry's Starter circuits.
You must test the ignition wires because there are 2 Black/Yellow wires. One is an Ignition type wire and the other is a Starter wire.
You're going to need a relay for the Trunk release so you might as well get a 4 pack of relays off EBay for ~$10. Search on "30/40 Amp SPDT relay 4 pack" and get the ones that come with harness socket.
Remember that the Tach wire shown at the OBD2 connector is for 4 cylinder Camry's only. Also verify that your Camry does not have transponder chipped keys. If they are, you will need a bypass module to allow a remote start up.
Soldering is fun!

Thanks Kreg!
Already have the relays, inline fuses and diodes. I plan to wire just like you did and I don't have to worry about a transponder key. LOL on the OP-500, you are right, $100+ for a programming tool that from my research unless you are a registered installer, they won't even let you update the firmware. I'll stick to changing options with the remote. My Camry is the 4 cylinder model so I don't foresee any issues. I'll be careful to double check the function of the wires for CON2/3. I laugh when I read reviews about having R/S only being installed by pros. I live in a small college town and I wouldn't trust these shops to install windshield wipers. They prey on the college kids and they figure if they ever changed out the stereo in a car, they can open a tint/R/S/stereo shop. A little common sense goes a long way.
Thanks again for the insight, I'll let you know how it turns out this weekend. I do have 1 question though. I plan to run tachless, which I believe is the default. Did you run into any issues with the way you set your Camry up? Also I think I can get by with only 1 starter relay, CON1 pin 5 blue wire can be configured by jumper to be ING, ACC or START. ING is default so I figure I put the jumper for START and run that wire to the STARTER 2 relay. Thoughts?
Cheers!

Personally, I always run in Tach Mode. With the Tach wire so easily accessible inside the car, you really should make that connection. Tach Mode is much more reliable getting consistent starts, especially in cold climates where the seasonal changes vary by 90 plus degrees.
You are already using the CN1 Pin 5 Blue wire for the Camry's IGN2 circuit. As mentioned above, that car has two Ignitions, two Starters and one Accessory wire that should be powered during remote start. I have heard that powering both ignitions from one R/S wire will blow a fuse in the engine compartment that will get the car towed back to the install shop. A little extra time adding the two starter relays during bench prep is the safe way to go.
I encountered no issues with those Camrys. They respond well to the aftermarket system. The only minor hurdle was finding and verifying the Trunk Release wire. You need a working Factory FOB to trigger that signal. They are fast and easy to do without an alarm system or need for a transponder bypass module.

Yep, you're right, I completely spaced the IGN2. I'll prep the harness Friday night and do the install Saturday. What is the best way to attach the diodes? Do you solder them to the blades on the relay or just to the wires for pin 85 and 86?
Thanks again Kreg!

For the relay quenching diodes, I add them to the 5 Pin wire harness as shown near the end of this Pictorial :     https://www.the12volt.com/installbay/forum_posts.asp?tid=133810
Keeps everything neat and, of course, I like to solder....     2002-2004 Toyota Camry Remote Start w/Keyless Pictorial -- posted image.
If you have the supplies available, you can use thinner gauge wire for the IGN2 and Starter2 ignition wires. Makes the soldered connection easier and provides a compact bundle of wires going to the steering column.
Good luck with the install.

You are the man Kreg! I was just looking at the CN3 harness and I might be screwed for the trunk release without having to get my hands on an OP500. I don't see a wire that by default will trigger the trunk. CN4 has everything I need so what I might do is scrounge up a connector that will work with that. The CM900 does not come with a wiring harness for CN4, it is optional for people upgrading from the CM800. Have a great day and I'll update you this weekend!
On a side note, I thought I was the only person in the universe using a Circuit Buddy! 2002-2004 Toyota Camry Remote Start w/Keyless Pictorial -- posted image.

Forgot about the Trunk Release being on CN4. I have the OP-500 so it's no problem for me. I also have a bunch of unused harness. I can send you a CN4 harness if you need. Just PM me your mailing address.
I get a lot of use out of my Circuit Buddy. Great probe with nice features. A PowerProbe would be nice but I really can't justify the cost.

I got it covered but thanks for the offer! I have a lot of wiring harnesses of different types left over from years of doing stereos for friends. Install is almost done, just have to hook up the locks and trunk and were should be ready to test.
Thanks kreg!
