1998 Trooper keyless entry ecu location?

Hello all,
Just bought another Trooper, my 4th a 1998 LS 90k with all the options, even the compass!(cool) anyway the remote ecu is no good, the previous owner did not want to have it changed, and I do,does anyone know where it is? better to ask than to take the dash apart and not find it!
Thanks!
:)

Hey all, found it, it's under the drivers seat, covered by the carpet. Thanks anyway.

What was your trooper doing that required replacement. My remote works once in a great while, and when I do lock the car even manually, the alarm goes off for no reason. Is that the problem you faced? if so, I assume replacing the ecu fixes that, so did you get the part from Isuzu?
