I've been told 3 different places. where is the engine computer located? under passenger seat, under the hood or behind glove compartment? thx

according to ALLDATA, the seat control memory module is under the driver's seat, no modules are under the hood and
the abs/trac module, engine ecu and stereo amp are all
behind the glove compartment
