2001 Toyota Camry, Factory Alarm Removal, Avital 5305L Install

Hello,

I've had a few recent break-ins and the stock alarm didn't alert me, so I'm beginning my security system upgrade this weekend.

I bought the Avital system, a battery backup, a tilt sensor, and a fuel door pin. I plan to wire these in myself. My car doesn't have a smart key, so I didn't purchase a bypass.

Today I spent some time removing panels and pulling out the old alarm harness, or what I thought was that. Afterwards, I tested the lock & unlock buttons on the Toyota fob to see if I was successful, but they still worked!

Because of that, I feel like there's still something in there that I need to uninstall before I put in the new system.

Does anyone know where Toyota may have hid something I'm not easily seeing?

Or is it even necessary to pull the stock keyless entry system out before adding a new alarm?

I see my new unit has listed a (-) 200mA FACTORY ALARM DISARM OUTPUT in the diagram. So maybe that overrides the Toyota keyless entry system, making the complete removal unnecessary?

Can anyone tell me if I'll need relays for the defroster, horn honk, parking lights output, or the dome light supervision? I'm already assuming I'll need them for headlights and taillights.

Thanks for any insight

I'm going to start with the main harness, 5-pin connector.

-I'll run the black to an existing chassis bolt.
-Then the brown to the siren and its ground to the same chassis bolt above.
-The red to the 12v constant in the ignition harness.
*The orange GWA output I'll set aside for now because I'm not sure what I'll do with it yet.
-Finally, I'll jump the white wire to (+) on the brain and connect it to the green (+) parking light wire under the fuse box.

I got those above wired up.

I've been searching for the negative power unlock/lock wires (blue & blue/white), but I don't see them. I metered all of the fuse box and only got readings from the lock/unlock motors (blue/red & blue/black).

Does anyone know if it's ok to just use those instead? If so, will it then require a relay?

I ended up finding the correct lock/unlock wires. They were green & light green, located in the kick panel. The vehicle diagram on this site was inaccurate in my case.

So yesterday I got those hooked up, as well as the door triggers, hood pin, and tach input.

I peeled the plastic off my 2-way remote to test what I've done so far... and everything works great at this point!

I'm wondering if anyone knows how to silent arm/disarm this unit?

Next I plan to wire up the trunk trigger input, horn output, and dome light supervision. Please correct me if I'm wrong, but I'm guessing I'll need relays for the last two.

Silent arm should be the aux button followed by the arm button. You could also just turn off the confirmation chirps in the programming menu.

Horn should be a negative trigger so you shouldn't need a relay for it. Dome supervision will need a relay.

My ex once told me I have a perfect face for radio.

Thanks for the reply. In that case think I will actually save this relay for another function; maybe a trunk solenoid. Seems like it would be more useful, since Camrys already have the option to illuminate the dome light on entry anyway.

I just finished browsing the programming menu and was wondering about code hopping; do you keep that turned on?

I just leave it on

Ok. Hey, how do you determine which wires will for sure need relays - trial and error? Sounds like units can vary in certain outputs being internally relayed...

Today I connected the trunk pin and parking brake inputs.

I also connected the brown/black (-) 200mA horn output, but it didn't function. I tried both green/black (-) wires in the steering column according to my diagram.

I tested both those with the multimeter while honking and only had a fluctuation of about .05 volts. I wasn't holding down the horn very long though, so I thought they were it.

Should I be seeing a lot more voltage loss when doing that and possibly have the wrong wires? Or do I need a relay to power the horn correctly?

Your manual should tell you the rating of the outputs. If an output is only rated for 200 mA current, it should only be used to drive a relay.

You may have better luck pulling your airbag to locate your horn wire. Then you can trace it back from there.

I thought the same about the parking lights ouput, but they flash just fine for some reason. Thanks for the suggestion. Tomorrow I'll wire in the tilt sensor to the GWA output and reattempt the horn connection.

Hey guys.

When I was getting out of the car, I accidentally armed it before my passenger shut their door, causing the alarm to trigger.

I disarmed it, rearmed it, then went on my way.

Later, I came back to the car and disarmed it to get inside, but the doors wouldn't unlock though.

Anyone know what would cause that?

At least the key let me in.

Can someone confirm that I have this harness properly wired:






2 red/black to ignition #1 black/red
3 pink/black to not needed?
4 pink/white to also not needed?
5 red to constant 12v white/red
6 green to starter #1 key side of cut red, and relay pin 30 red
7 violet to starter #1 starter side of cut red, and relay pin 87a white, and relay pin 86 orange
8 orange to accessory #1 blue/red
9 red/white to constant 12v white/red
10 pink to ignition #1 black/red

Here is the wiring :
Remote Start, White 10-pin heavy gauge connector
1 No Connection
2 RED/BLACK (+) FUSED 12V ACC/STARTER INPUT          White     
3 PINK/BLACK* (+) IGNITION 2 pin 87a   not used       
4 PINK/WHITE (+) IGNITION 2 / ACCESSORY2     Black/Yellow
5 RED (+) FUSED 12V IGNITION 1 INPUT              White/Red           
6 GREEN (+) STARTER INPUT (KEY SIDE)            Red key side of cut wire   
7 VIOLET (+) STARTER OUTPUT (CAR SIDE)       Red    car side of cut wire             
8 ORANGE (+) ACCESSORY OUTPUT            Blue/Red
9 RED/WHITE (+) FUSED 12V IGNITION 2              White       
10 PINK (+) IGNITION 1 INPUT/OUTPUT Black/Red

Not positive what you are doing with the external relay but if it's for Starter Kill and Anti-Grind, the 5305L has that built in and that is why you have the Violet and Green wires.
On the Viper controller any wire with a fuse is a +12V input wire and all will be used. This would include the Red wire w/fuse on the 5 Pin harness. You can connect it to the Camry's White/Red wire, too. That way the Vipers load will be split between the two +12V vehicle wires.

-------------
Soldering is fun!

Hey, thanks for revising that for me. I wonder what I'd have created had I wired it that way.

I assumed the kill switch needed a relay and didn't consider it having one built in. I think seeing the relay numbers for its pins in the diagram reinforced that idea.

I want to add a 507M tilt sensor and a 520T backup battery to this system.

It looks like they'll be sharing the same trigger wire on the alarm, so it's my understanding each of them will need a diode in line with this wire.

Can I get someone with experience to let me know if my following plan here looks good to go?


Here's my alarm's diagram:


This is the tilt sensor diagram:

Would it just go like...
red to #3 on main harness
orange to #4 on main harness
blue to #10 on aux harness (diode in between and stripe towards alarm brain)

The backup battery diagram shows what I think is another diode in line with the brain's constant power wire. If so, I assume the cathode stripe is to be on the side of the alarm?

Do these connections seem right?
red to car battery positive
gray to #3 on main harness (diode in between and stripe towards alarm brain)
black to chassis ground
blue to #10 on aux harness (diode in between and stripe towards alarm brain)

Thanks in advance!

Guess I should start a new thread for that last question since it's been a while since I added to this subject. I just figured here was fine because it was related to my original project.

Any pros on here who can direct me through this?
