I need help wiring my keyless entry into my 1990 Lexus ls400. Can someone instruct me on how to do this from the keyless area in the trunk, where the wires are put into the original receiver. I have pulled all the wires out of the original receiver in the trunk, but am not sure which one I should put with which. I have attached the diagram that came with the keyless entry system I bought.

 

All i can tell you is that when i had mine installed on my 92 the place installed it in the dash not the back trunk. It tied in to the factory alarm system. My keyless remotes didnt work anymore so thats why i bought a viper keyless. Cost me about 125.00 or so installed with horn honk and light flash.

Took the installer about an hour or so.
