GEM?? Where is it

[Boney Collins]

Some where here I posted about the dome light not going off, so I found the relay box that is inside de cabin. Now the proble is that the GEM (Generic electronic module) is not cutting the ground from the relay that turns on-off the domelight.
Now as i said, when de the key is on the On position the domelight works right, but when no key.. it stays on (I have cheked door sensors)

WHERES THE GEM MARKED ON THE PICTURE WITH RED on the truck.

thanks.

The GEM module is located behind the radio. Its on the left side of the opening mounted vertically. It had five electrical connectors on it. Three on the side, one on top and one on bottom.
