I installed the Crimestopper 2016fm in my 2000 Toyota Tundra. I could not get the door lock or unlock to work. I have the power lock as being WHITE/ green in the Driver Door Harness.The unlock is RED / yellow and it is isolated with a diode with the child safety wire blue/black. Where exactly is the driver door harness? Do i have to take off the cover? I tapped into the wires out of the door and in the front kick panel. This did not work. I ckecked the voltage at the switch and it did get a negative pulse from the alarm but the motors did not activate.Where is the relay located? I am not sure if this car had keyless entry from the factory, but should it matter?

When you diode isolated the unlock wires, you isolated both unlock, and the child safety wire with individual diodes right? And both diodes are tied together leading to the alarms unlock wire.
The lock wire does not need to be isolated with a diode, just tap into it with the alarms lock wire.

Dont know why I got booted off, but here is the rest.
Lock wire is WHTITE / GREEN.
Unlock wire is RED / BLUE & BLUE / BLACK both of these wires must be diode isolated and wired together for them to unlock properly.

Yes, I diode isolated both of them and the wire colors you provided match the ones I used. It still doesn't work. Maybe it's where im tapping into. The diagram i have says the driver door harness(where is this located?). I tapped into the wires that come out of the door through the rubber sleeve.

The wire is not RED / YELLOW . . . Please check and verify the proper wire is connected to.

LOL, Directech says the same thing. Wire Magic is what I am referencing too. Let me look up two more data bases.

Silly question, which direction are the diodes facing? The cathode or band side should be facing the alarm module.

Yes the cathodes are facing the alarm module to allow negative flow to the lock/unlock wires. I test the wires that i connected to and they do get a negative pulse from the alarm module(same as the pulse from the driver switch). Any word on the wire colors? Also are the relays in the kick panel or under the hood? Thanks for the help Where is this info from:

R U using Relays for Negative Pulse to Lock / UNLock? or R U using wires from RS / Alarm module?
This is for Driver Unlock first information
The Factory Relays R built into the Integration Unit at Driver Junction Block | RKE Module | NO OEM KEYLESS PRESENT IN SCHEMATICS | | | Motor Lock | BLUE/WHITE * | AT RELAYS | | Motor Unlock | BLACK / YELLOW * | AT RELAYS | | Drv Door Unlock | BLACK / YELLOW * | 12 PIN CONNECTOR DRIVERS KICK | | OEM Relays | BUILT INTO INTERGRATION RELAY @ DRIVER JUNCTION BLOCK |

Im using the wires from the alarm module. So should i connect the lock wire from the alarm to the blue/white wire from your table, and the unlock wire to the BLACK / YELLOW wire. What about the child safety wire?

The above post is ONLY for Driver Priority hook-up using External Relays, so ignor
The wiring U posted looks correct.
Did U meter Factory wires to make sure they R correct? Have U tried Ground to Lock / UNLock wires prior to hooking up RS / Alarm
If U hooked up RS / Alarm wires Direct to Factory wires, U may not be getting a strong enough Ground Pulse & U may need to use 2 SPDT Relays

The thing is that when i meter the wires, they show the same thing as the lock switch in the door except that the motors dont run.I metered the wires at the front kick panel, in the fuse block above it, and at the door switch and they all show the same thing. Is there a door ecu or wires from the key cylinder behind the door panel that i have to interface with?
