Alright my bro just got an 89 K5 Silverado ed. My k5 isnt a silverado so i we were wondering what the heck is the thing that is next to the engine compartment light that says Retract with a lil like knob to turn. Its on the firewall.


.IIRC it has 20 or 25ft of cord so it can reach the rear wheels with no problem..
