I need a fuse box diagram for a 1991 lexus Ls

There are 2 fuse boxes on the Lexus. The first is the main power distribution box and is located right beside the battery under the hood. The second panel is located behind the plastic kick panel under the dash on the driver's side where your feet go. The panel is vertical and covers the area from the dash to the carpet on the floor, just forward of the door. I can't remember if it's a pull off or if there is plastic twist nuts holding it, so check carefully before pulling on it.

The large part of the cable goes to the post on the starter. The smaller wires go to various connections including the main fuse box.

Should be under the hood. The manual should tell you where it is located. You can also calll the dealer.

check the wiring harness beside the hinge that moves when you close the trunk.i have seen the wiring get pinched and the ground gets broken. the tail lights have separate left and right side fuses.get a test light,and with the ignition in the on position,there should be power on both sides of all the fuses.the atc type have little test pins on them.ground the test light and put the tip on the fuse.if there is power,the light will come on. if a fuse does not light up the light on both sides,it is open.since the fuses are see thru,it is apparent if it is blown as the metal inside will be burnt.

under hood. you have to raise up the box and flip open side covers to unbolt 120 amp fuse.
