How do you reset the maintenance light on a 1989 Dodge Dakota?

well the first thing i learnd about about these trucks is try unhooking the battery for ten seconds,if that dosent work try un hooking the computer,i know it sounds redicules but it has worked for me in the past ....Dodge is the only vehicles that ill even buy anymore,way easy to fix and parts are a dime a dozen........Hope this works for you as it did me.......GOOD LUCK
