Does anybody know if a integration relay from a 92 es300 will work in my 1990 Lexus Ls400, because mine is blown?

Kick panel fuse box.

Been fitting LEDs in the interior lights by any chance?
When you say it has blown what exactly is happening with the lights?
The usual cause of failure is the fuse resistor fitted inside the unit costs around 50 cents to buy and a bit of soldering.
There is a difference between the 90-92 and 93-94 models so you would have to check the part number against the ES unit.
It's also a pig to replace as it is clipped to the back of the fuse panel below the dash.
