Facing the engine, low left side of the engine .
There are two models of the Lincoln Mark VIII. The base or standard MARK VIII and the Mark VIII LSC. The LSC was introduced halfway through the 1995 model year, and continued to the end of the Mark VIII production. SRS refers to the SUPPLIMENTAL RESTRAINT SYSTEM (air bags). This is why you may see the letters SRS on the panel above the glove box area and on the steering wheel horn pad.
In my 95 Mark viii there is a little access panel on the left side in the trunk, its in there. (its a little red switch.)
