Chirps not working in valet 562t

I am in proess of installing the valet 562t in 95 camry.. i installed most of the things just Horn is not working.
When i unlock or lock the car the parking lights goes off my no sound.

i Plug the brown wire from the brian to the GREEN/ black wire at steering wheel colum harness. i double check with 3 different sites and they all say that GREEN/ black is the horn negative wire.

the default setting is the chirps is on so i am guess that it is not in silent mode.

Does anyone know why it is not working?

test the wire. make sure it reads ground when you honk the horn. make sure the brown wire is pulsing not constant also.

I still have trouble ppl hooking up wires without testing. What if you accidently hooked up to a PATS wire or a gauge cluster wire and shorted it out. You would not be very happy with the $1000 fix.

Sometimes DIY sites are good, but not if ppl are just blindly using the information without actually knowing what they are doing at all. Hooking wires blindly to wires that some websites list is just asking for trouble. Maybe not the majority of the time, but it will happen.

I have seen posts.... I didn't hook up the white 2nd IGN on my chevy truck and my tranny went out....

It says the black wire at the BCM for park lights.... so I cut the 6 black wires until my park lights didn't come on anymore and knew it was the wire.... now my gauges don't work and air bag lights are on all the time.

It said the orange wire in my Olds Cutlass Ciera.... I tapped the orange wire in the white sheathing (there was orange and white) and now my car won't start.

It said my starter was the yellow or purple wire... i didn't see a yellow, but I saw a thick yellow sheathing and cut it.... My air bags deployed.

Wat if i get the wire from the horn in the hood and use that, if it is postive i will use the relay shown in the manual and if negative i will just connect that with brown wire from the brian


does anyone know war polraity is the wire. there is only is 1 wire.

ok i just checked it

my red pin of DMM is connected to the wire at the horn under the hood and the black pin of my DMM is connected to ground. So when i hit my horn my meter goes from 0v to around 12v.that means this is positive trigger..

then i checked my output out of the brian and it is negative trigger.. i have plug into the GREEN/ black wire in the steering coloum but it doesnt work.. so i am going to put a relay and change the in to positive trigger and attach to the wire from the horn under the hood...

Anyone know how to use relay in this case?

thanks alot for you repsones..

i think i found the diagram.. i need use the first relay diagram shown on this webpage

https://www.the12volt.com/relays/page1.asp#n2p

ok after testing the wires with Dmm i plug the horn with relay

86 and 30 -- constant 12V
87--- Positive trigger into the horn under the hood
85-- negative brown wire from the brian

But my horn still DOESNT work.. i dont understand why

my brian give negative trigger output and horn takes positive trigger.

i am not using the green.black wire under the steering wheel because that is not a right wire and i dont want to mess anything up becuase i read some horrible stories on these posts

so anyone have any idea how to get my horn to working with my valet 562t

thanks

it only has 87

i dont know wat n/o or n/c means
but in the relay there are 4 pins 86,87,85,30

there is notting in the middle of the relay..

ohh okay i have another relay at home that has both 87 and 87a

so which pin should i Use for the positive output?...

bTW the relay that i am currently using from radioshack, the pin 87 is n/o

I had the relay in the configration but still doesnt not work.. i have check the horn wire under the hood 3 times but i realize that my brain give "(-) horn honk output" not negative 12V...

thanks you very much for replying

yea the pin 87 is positive 12v output to the horn

yea the pin 87 is positive 12v output to the horn

Thank you very much i got it work.. i found another wire in the steering wheel that was GREEN/ black

and i works fine

thanks alot of your help
