Post by: marandall on October 29, 2012, 10:04:13 pm

hello everyone just recently started a project on my 79 Chevy k20 pickup and i am swapping out the cabs with an 80-81 model cab and when i was looking over the new cab i noticed that there is a gray electrical compent (gray box ) under the dash if you were looking at the dash front the driver seat it will be located right behind the instrument cluster to the right does anyone have a clue what part that is and whats it purpose i have a a Haynes repair manual but i cant find anything in the wiring section that describes or shows me what the part is or i could just be over looking it since i really don't know what it used for....Any comments would help please thanks for taking the time to read my post

Is there a sticker attached to the box bearing a GM part number?
