1987 4000S OXS light reset

[James Dupree]

1984 and earlier have the mileage counter that inline in the speedo cable. 1985 and on have the counter built into the speedo head. 
On the backside of the instrument cluster, on driver side top there is a small opening labeled OXY. Reach in with a small flat bade screw driver and press the release levers. You can hear the spring loaded mechanizm rest with a slight thud. The opening is about 5mm wide and the blade can only be 4mm thick or so. You don't have to pull the instrument cluster loose just take the cover off and look thru the windshield at the back of the cluster.
Good luck
Jim

Under the top cover for the instrument cluster, isn't there a push button 
reset along the speedometer cable which is calibrated to ~30,000 miles, which 
triggers that light? I've never done it myself.
