all you need to do is unplug the motor to the hicas to eliminate it
crawl under the rear of your car and you will se the motor near the diff
unplug the wires(hicaslight comes on ) and hicas is disabled
you may think that it will move freely now,,,wrong the motor wont move at all its locked into position internaly untill its told to move
the lockout kits are expensive because they have a curcuit to fool the hicas computer into thinking its still working so you dont get the hicas light coming on thats all
