1989 L-series touring wagon "Check Engine" light

The panel under the dash board comes out. Remove the plastic screws to get in. This panel clips onto the steering column shaft towards the rear. The LED lamp on the ECu may be visible between the foam under the steering column where it goes into the dash.

Ther would be 2 black plugs with a singe wire on each end to plug un towards the back of the ecu near the pedals, if i recal. Ithis is the "ECS' light on the dashboard.

The 'oxygen monitor' mounted in the trunk applies to XT coupes
