Now is the time to disconnect the main underhood wiring. This Powertrain Control Module (PCM) for the Corvette is located inside the passenger fender, so you need to get into that area. Instead of removing the entire fender, you just need to remove the lower fasteners to tilt the fender up. This is accomplished by removing the seven 7mm bolts and one plastic pushpin holding the splash panel on the passenger-side front fender. Then, remove the two 7mm bolts at the bottom edge of the fender.
