1999 lexus altezza door locks

wat's up guys, i have a problem, i did an altezza today starter alarm combo, viper 791xv, everything went smoothly except for the door locks, i don't have a tech sheet, but i've been doing toyotas for a long time, and since the vehicle was made in 1999 i assumed for sure it would be negative trigger, but for the life of me i can't seem to find the appropriate wires even at the rocker switch controls on the driver door panel, i've tested, tested and retested but can't seem to pick up a reading, can anyone shed some light on the topic any help would be appreciated. there's a bcm in the driver kick panel that has the door lock relay inside, but the connector comes into the bcm from behind the panel so removing the module to test has proven futile.

I think they called that car the IS here in the States. There's a special diagram to control the doorlocks with one relay and two diodes, wired up inside the driver's door. I would think maybe your car would be the same as what we have here, not sure. I think somewhere on this site you can find that diagram. Do a search for some of the following cars: Toyota Highlander, Sequoia, Avalon,   or Lexus IS250.

thanks chris, any links you could reccomend, thanks again.

thanks alot man, appreciate it, i'll see if it works when the customer comes back in,
