Question: How do I access the wires from the evap canister vent valve wiring that runs between the pigtail connector on the rear passenger side and the PCM on a 2006 Cobalt LT? Is there an access panel or heat shield underneath the car I need to remove in order to expose it, or is there an interior component I need to remove?


Background:
I have traced down an evap problem I am having (P0449 and P0452) to a faulty ground connection between the evap canister vent valve and the PCM (I tested where the evap canister pig tail connects at the back of the car). Since I cannot visibly see where the wires go, I want to find out before I start tearing the car apart to access the wires and I cannot find the information from any amount of Google search terms I have tried.

In case anyone else is curious: The wiring runs along the interior starting under the rear passenger-seat, continues up along the passenger side/floor trim pieces and then appears to route to the driver-side once the front seats are reached (I stopped hunting in the interior at that point). My particular problem was related to the wiring inside the engine compartment just before reaching the PCM
