i also have an 1990 ls 400 with ignition wirind promlems. i searched for a few weeks and tried to get the diagram through various mechanics. they all ended up telling me that the dealership would not provide them with it. so, the Lexus dealership is just about the only place to get the wiring diagram. your question was not very detailed so i may not be giving the answer you need. the problem with my auto is that the key will not turn past the "on" position, if this is the case then the easiest solution is to hotwire the starter. this is possible by connecting the positive terminal on the starter syleniod using jumper cables and then turning the key to "on". once this has been set up; simply touch the other positive clip on the jumper cables to the positive terminal on the battery. this should start the car. -CoNtRaFoRm-
