problem with 03 tundra alarm

ok i spent the most part of yesterday tryin to figure this out, got a cheap alarm system on ebay to put into my 03 tundra, cant get the doors to do anything have all the wires (thanks to this site) i can make the doors unlock by hitting 12 v on the WHITE/ blue in kick panel but cant make it do anything else, beginning to think theres somthing wrong with the alarm but if i can make the doors unlock by putting volts or grounding to a wire then how would the alarm do it. please help im at my wits end thanks greg

Does the alarm you purchased have selectable polarity for the door locks? Usually there is a jumper or a fuse you move between two positions to select the door lock polarity (pos or neg)

yes it has diffrent wires for - or + for locks, what i cant understand is why i cant hit the lock wires with + or - and can only unlock doors but not lock them, if i can find this out im sure i can figure the rest

Lock = WHITE/ green Unlock = blue/red Both neg both driver's kick well, loom coming in from door, just set your lock wires as neg., job done.

That was Directechs and Bulldog, A/Vox makes it orange and BLACK/ blue at the fusebox.

thanks much guys after much work i can now lock and unlock doors with neg wire, turns out its the wonderfull alarm i bought on ebay.. the door wires from it do nothing no pulse no nothin .. so off to email the seller..

Can you post the unit's circuit diagramme.
