i previously installed an alarm on a 2003 camry. however, i had problems with the doorlocks. i read on two different tech sheets that the lock wire was blue / YELLOW & the unlock was blue located in the driver kick. i checked all the wires with a multimeter and a computer safe tester coming out of the door firewall and the wires controlling the doorlocks appeared to be different in color from the sheets. the doorlocks didnt work so i tried using relays with 12v on 85 doorlock wire from alarm on 86 ground on 30 and doorlock wire on 87 and it still didnt work.. i then took the doorpanel off and wired the alarm doorlocks directly to the harness on the door and it still didnt work.. i ran relays there too and still didnt work

does any one know of anything else i can try or why its not catching.. is there something im missing or forgetting to do?

you have to make sure you are testing the wires with your DMM by turning the lock cylinder in the driver side door. they will not test using the switches, lock cylinder only. that is the only way you are going to find the correct wires you need to use. negative trigger, and double pulse for unlock.

Power Lock

blue / YELLOW

driver kick, door harness

These wires will meter while turning the key in the driver door key cylinder.

Power Unlock

blue (double pulse)

driver kick, door harness

These wires will meter while turning the key in the driver door key cylinder. Can also use the passenger door key cylinder wire for unlock, which only requires a single pulse. It is blue/white (-) in the passenger kick, door harness.

Measure your output voltage from your unit and make sure it is even sending a negative pulse?

Other than that I would say verify your wires. And turn key in cylinder like stated before.

This above is correct.

There are two other wires that test using the rocker switch on the door panel, but don't use those.

Definitely test while turning key in door from outside.
