I was needing to know how to install a computer in my buick riviera?
What I mean is where to install the bcm.

i have a 88 olds and mine is probably the same as yours and i put 1 in mine. what i did was i took out the glove box and there it was stuck up between the heater box, i unhooked the battery and theres a nut hooked on a hanger, you take off and the computer drops down, and unhook the harness and its reversal of removal, you cant get the harness backwards, because they only hook up 1 way, thenafter you get it installed, put the glove box back in and wait for a while before hooking up the battery.
