Reset maintenance required light

[SGBARRACUDA]

Ok on a 1990 D-150 I have the "maintenance required " light on and need to reset it. It seems that i remember a little button under the dash that you push but I really don't remember. Anyone help me out?

My friend has fair knowledge about maintenance and I will ask him to solve your query.
